    SYNOPSIS

           fd  [ -abCefhiklmNnPrSsTtuvx ] [ -NAME=value ] [ directory [ directory2
           ...  ]]
           fdsh [ -abCcefhiklmNnPrSsTtuvx ] [ args ]
    
    
    

    DESCRIPTION

           Fd is a file & directory maintenance tool considered for the text  ter-
           minals  on general UNIX.  It aims for a clone of the same named utility
           which is made for the PC/AT compatible machine and PC-9800 series.   In
           fact, it is upper compatible functionally.
    
           Fd  shows  the  browser  screen listing files when you have invoked it.
           You can input some key which is bound each command, to execute  various
           operations.
    
           (In  the  following  description,  (UNIX)  means  that the operation is
           implemented only on UNIX version and not effective on  MS-DOS  version.
           As  well  as  it, (DOS) means that the operation is implemented only on
           MS-DOS version.)
    
       Options
           The command line option is used for setting internal  shell  operations
           and  setting  the  internal variables described below.  You can use any
           variable name as the internal variable, but fd can  accept  only  those
           which  are described in the below section of ENVIRONMENT VARIABLES.  If
           you specify directory, the current directory is moved to the  directory
           initially.   If  you  specify  directory2 ..., the split window mode is
           invoked, and the current directories of the  supplemental  windows  are
           moved to the each directory.
    
           The following options are available for the internal shell.
    
           -c string
                  Commands  described by string are executed and exit immediately.
                  It is effective only when it is invoked as fdsh.
    
           -i     If the -i flag is present or if the standard input/output  is  a
                  terminal, the shell is the interactive shell.
    
           -s     If  the  -s flag is present or if no args is specified, commands
                  for the shell are read from the standard input.   Any  remaining
                  argument specifies the positional parameter.
    
           -r     The  shell  is  a restricted shell.  Specifically, the following
                  operations are disallowed.

       Screen Layout
           Fd has the 3 major screen modes.  In the browser screen, you can select
           from  the  file  list and execute each command.  In the archive browser
           screen, files in the archive file are listed separately  by  directory,
           and  you can browse as well as the browser screen.  In the tree screen,
           you can move on the directory tree and select the directory path.
    
           In all screen modes, each 3 lines on the top/bottom of the  screen  are
           used  for  the  various  information  of fd.  The top information lines
           sometimes become 4 lines.  The screen layout is the following.
    
           line#     Description
    
           1         The title line.  The clock at the right end is updated  every
                     10 seconds.
    
           2         The information line.  It displays information in this order:
                     the current page (and the total pages), the number  of  marks
                     (ant  the  total  marks), the sorted type, the pattern string
                     for file search.
    
           3         The path line.  It  displays  the  fullpath  of  the  current
                     directory.   In  the  archive browser screen, it displays the
                     fullpath of the archive file and  the  current  path  in  the
                     archive.
    
           2 (optional)
                     The  file  size information line.  It displays the total size
                     of the marked files in the directory (and the total  size  of
                     all  files), the total capacity and the free size of the file
                     system including the current directory.  This line appears by
                     SIZEINFO  the  internal  variable setting.  When this line is
                     displayed, The information line and the path  line  are  dis-
                     played 1 line under each.
    
           bottom - 2
                     The stack line.  It displays files temporarily which you push
                     in stack, when arranging files.
    
           bottom - 1
                     The function line.  It displays the  operations  of  function
                     keys.
    
           bottom    The  status  line.  It displays the status of the file on the
                     cursor position.  It also displays warning messages when com-
                     mand is executed with some troubles.
    
       Internal Commands
           You  can use the following internal commands on fd.  While any user can
           change the key binding for these  internal  commands,  here  shows  the
           default  key  binding.  The identifier is used when it is executed from

           The detail of each internal command is the  following.   Internal  com-
           mands with similar function are described together.
    
              Move cursor
                   Move a cursor.
    
              Turn page
                   Turn  to  the previous/next page, when files are not completely
                   held in a screen.  Also if you try to move out of the page with
                   Cursor move, the page will be turned.
    
              Move to the top/bottom
                   Move  a  cursor  to  the top/bottom of the file list.  When the
                   list is not held in a screen, the page is turned.
    
              Shift filename
                   Shift the displayed string of filename on the cursor  position,
                   when the filename is longer than the prepared column width.  It
                   is displayed as shifted to right/left by 1 character.  The dis-
                   play of the status line is also shifted simultaneously.
    
              Change layout
                   Change  the  number of columns into each value.  There are usu-
                   ally 2 columns per screen.  As the column  width  per  file  is
                   changed  according  to  the  number  of  columns, the displayed
                   information is also changed.
    
              Mark file
                   Mark the file on the cursor  position.   You  cannot  mark  any
                   directory.   [Space]  marks  and moves down a cursor.  [^Space]
                   also marks and moves down a cursor, but doesn't turn the  page.
                   [Home]   marks  all  the  files,  [End]  marks  all  the  files
                   reversely.  [*] additionally marks the file which  matches  the
                   wildcard.  You must input the wildcard string whenever you push
                   [*].
    
                   Marked files are used as the target  of  ATTR_FILE,  COPY_FILE,
                   DELETE_FILE,  MOVE_FILE,  UNPACK_FILE and the user defined com-
                   mand macros.
    
              Change directory
                   [Return] changes the current directory to the directory on  the
                   cursor position.  If you want to change it to the parent direc-
                   tory, you should move a cursor to the file  of  ".."  and  push
                   [Return],  or simply push [Bs].  [\] changes the current direc-
                   tory to the root directory.
    
              Push/pop file stack
                   [Del] pushes the file on the cursor position to the file stack,
                   and  temporarily  deletes  the  file from the file list screen.
                   You can push files to the file stack up to 5 files.
    
    
              Change logical directory (Logdir)
                   Change the current directory to the  inputted  pathname.   When
                   you  input the pathname which starts with '/', it means not the
                   relative move but the absolute move.
    
                   When you input the pathname ".", the pathname  of  the  current
                   directory  is  adjusted  into absolute expression.  Except this
                   case, the current directory always  is  shown  as  the  virtual
                   pathname,  by  reason  of a link and so on.  When you input the
                   pathname "?", you can move to the current directory when fd was
                   invoked.   When you input the pathname "-", you can move to the
                   last visited directory.
    
                   Moreover, When you input the pathname "@" in floppy drive,  you
                   can  move  to  the  directory  on  UNIX  file system, where you
                   existed before moving to floppy drive.  (UNIX)
    
                   (Note: This command is called as "Loddsk" in the original FD on
                   MS-DOS,  which  is short for "LOGical DiSK drive".  This "logi-
                   cal" means the drive name prefixed to pathnames, and it is vir-
                   tually  named  against  "physical  disk drive".  On UNIX, since
                   "logical disk drive" never means pathname nor  directory,  this
                   command  name  "Change logical directory" is not suitable.  But
                   this name is expediently inherited from the original  version.)
    
              Execute file (eXec)
                   Execute  the  file on the cursor position with some parameters,
                   as the child process.  The  cursor  position  in  command  line
                   exists  after  the filename in case of the executable file, and
                   before the filename except it.  You should fill suitable param-
                   eters  or  command  name in each case.  The up/down cursor keys
                   can provide the command history which you executed before.
    
                   On MS-DOS version, the LFN form filename in  the  command  line
                   which  is  quoted  with  the  quotation mark " is automatically
                   replaced into 8+3 form  filename  before  execution.   In  this
                   case, when there is the filename described by the string quoted
                   with ", this string is always replaced into 8+3  form  filename
                   after deleting ", otherwise it is never replaced including ".
    
              Copy file (Copy)
                   Copy  the  file  on the cursor position to the specified direc-
                   tory.  When the cursor position indicates a directory, its con-
                   tents  are copied recursively.  When some files are marked, the
                   target is not the file on the cursor position  but  the  marked
                   files.
    
                   When  the  same  named  file exists in the destination, you can
                   select the operation from the  following:  "Update  (by  times-
                   tamp)",    "Rename    (each    copied    file)",   "Overwrite",
                   "Not_copy_the_same_name", "Forward".  If you select  "Forward",
                   the same name as any existent file.  When you specify the path-
                   name with some directory name, it is also moved to  the  direc-
                   tory.
    
              Sort file (Sort)
                   Sort files in the current directory.  You can select the sorted
                   type  from  the  following:  "fileName",  "Extension",  "Size",
                   "Timestamp", "Length (of filename)", and specify "Up (incremen-
                   tal order)" or "Down (decremental  order)".   When  the  sorted
                   type  before sorting is the one except "No chg (not sort)", the
                   choice will include "No chg".   When  you  sort  after  sorting
                   another  sorted  type,  the  previous sorted result is based in
                   sorting.  This sorting has a priority  except  specified  type,
                   the  directory is always precedes any file, except for the case
                   of "No chg".  In case of "Length", files which  have  the  same
                   filename length are sorted in order of their names.
    
                   But  this  sorting  is  expediently  displayed in fd, and it is
                   reset by Directory move.
    
              Find file (Find)
                   Find the files matching the wildcard, and  display  only  them.
                   The  filename which starts with '.'  doesn't match the wildcard
                   which starts with '*' nor '?'.  If you want to cancel the  File
                   find,  you  should  move the current directory, or do FIND_FILE
                   again and input a null line.
    
                   When the current directory has the files which have the  exten-
                   sion  registered  to  associate  with  an  archive browser, the
                   string which starts with '/' is used to find not  the  filename
                   but  the  filename in archive files, and only the archive files
                   which contain matched files are displayed.   This  function  is
                   available in the archive browser.
    
                   After Find file, you can not do WRITE_DIR.
    
              Display tree screen (Tree)
                   Display the directory tree based on the current directory.  You
                   can select the directory in the tree screen, to move  the  cur-
                   rent directory.
    
              Edit file (Editor)
                   Edit  the  file  on  the  cursor  position.  The editor is used
                   referring EDITOR the internal variable, or referring EDITOR the
                   environment variable when the internal variable is undefined.
    
              Unpack file (Unpack)
                   Unpack  the archive file on the cursor position into the speci-
                   fied directory.  In builtin configuration, you can unpack  only
                   the  tar  file  and  its compressed file and the LHa compressed
                   file.  You can describe configurations in the initial  configu-
                   ration file to support archivers except these.
                   If the target is the marked files, [m](Mask) will mask a bit on
                   the cursor position with '*', to keep the value of the original
                   file  attribute.  When you input the timestamp, you move a cur-
                   sor to the position you want to change,  and  input  a  numeric
                   value.   When  you  input the owner/group, you move a cursor to
                   the position for each name, and input a name or a ID value with
                   [Space].   You  can  use  the  completion for a user name and a
                   group name to input each name.  Finally, [Return] executes  the
                   change.   You can cancel with [Esc].  Be careful that the limit
                   check of date is not perfect.
    
                   Moreover,  [a](Attr),  [d](Date),  [t](Time),  [o](Owner)   and
                   [g](Group) move a cursor to the each beginning of input line.
    
                   On the OS which has the attribute of file flags, you can change
                   the file flags as well as the mode.  In  this  case,  [f](Flag)
                   move  a  cursor  to  the beginning of input line of file flags.
                   But the value of flags which you can change is  based  on  your
                   permission.
    
              File system information (Info)
                   Display the information of the specified file system.  When the
                   inputted pathname is not the special  file  which  indicates  a
                   file  system,  the information of the file system including the
                   pathname is displayed.
    
              Move file (Move)
                   Move the file on the cursor position to  the  specified  direc-
                   tory.   When  the  cursor  position  indicates a directory, the
                   directory itself is moved.  When some  files  are  marked,  the
                   target  is  not  the file on the cursor position but the marked
                   files.
    
                   When the same named file exists in  the  destination,  you  can
                   select  the  operation as well as COPY_FILE.  When the destina-
                   tion belongs to the different file system, copy and delete  are
                   just executed continuously.
    
              Delete directory (rmDir)
                   Delete  the directory on the cursor position recursively.  When
                   the directory in a symbolic link, only the link is deleted  and
                   the linked directory has no effect.
    
              Make directory (mKdir)
                   Make  the  sub  directory  on  the current directory.  When the
                   inputted sub directory string includes '/', which is the  path-
                   name  delimiter,  it goes on making directory recursively until
                   the directory described by the string is finally created.
    
                   When you input the pathname which starts with '/',  the  direc-
                   tory  is  made not on the current directory but on the absolute
                   path described.
                   refer the clause of 'Builtin Commands' for the details  of  the
                   builtin command.
    
              Write directory (Write)
                   Write  the  displayed  directory.  The gap between files on the
                   directory entry is filled.  When it is executed after  arranged
                   by PUSH_FILE, POP_FILE and SORT_DIR, the result is written.
    
                   When  the  displayed  directory doesn't belong to the hierarchy
                   under your home  directory,  you  are  confirmed  for  security
                   whether  if any other user doesn't use the directory.  Since it
                   is insecure, you cannot write the  NFS  mounted  directory  and
                   some special directories.
    
                   If  you  execute  the  internal command which arranges the file
                   order, and then try to execute the internal command which  will
                   break  that  order,  you will be confirmed whether if you write
                   the directory or not, just before the internal command is  exe-
                   cuted.   For this function, you can write the directory without
                   intentionally executing this Directory write command.  But when
                   the  displayed directory is not under your home directory, this
                   confirmation is not done.
    
              Backup tape (Backup)
                   Backup the file on the cursor position into the specified stor-
                   age  device.   When  the cursor position indicates a directory,
                   all of its contents is backuped.  When some files  are  marked,
                   the  target  is  not  the  file  on the cursor position but the
                   marked files.
    
                   Tar(1) is used for  backup.   When  you  specify  the  filename
                   except  special  files indicates devices as input of the device
                   name, the archive file is created with that filename.
    
              View file (View)
                   View the file on the cursor position.  The pager is used refer-
                   ring  PAGER the internal variable, or referring PAGER the envi-
                   ronment variable when the internal variable is undefined.
    
              Pack file (Pack)
                   Pack the file on the cursor position into the specified archive
                   file.   When  the cursor position indicates a directory, all of
                   its contents is packed into the archive file.  When some  files
                   are  marked,  the target is not the file on the cursor position
                   but the marked files.
    
                   According to the extension of the inputted  archive  file,  the
                   associated archiver is automatically selected.  In builtin con-
                   figuration, you can pack only the tar file and  its  compressed
                   file  and the LHa compressed file.  You can describe configura-
                   tions in the initial configuration file  to  support  archivers
                   except these.
                   rent directory, and move the directory  where  the  found  file
                   exists.   When  the  cursor  position indicates a directory, it
                   find the file  under  the  directory  on  the  cursor  position
                   instead of the current directory.
    
                   You  will  be  confirmed  for each matching file whether if you
                   move or not, and you can select [n](No) unless the target  file
                   is displayed.
    
              Change attributes recursively
                   Change  attributes  the directory on the cursor position revur-
                   sively.  As well as changing attributes of  the  marked  files,
                   you  must  select  the  mode, the timestamp or the owner/group,
                   before changing it all together with each file under the direc-
                   tory.
    
                   When  you  input the mode, you should notice that the attribute
                   of the execution bit is not a triple toggle but a 5-states tog-
                   gle,  which  includes  'X'  and '!'.  'X' means setting the bit
                   only if the object is a directory or some  execution  bits  are
                   set.  '!'  also means unsetting the bit only if the object is a
                   directory or some execution bits are set.  [m](Mask) will  mask
                   a bit on the cursor position with '*', to keep the value of the
                   original file attribute.
    
              Invoke launcher
                   [Return] executes the operation according to the  extension  of
                   the  file  on  the  cursor position, unless the cursor position
                   indicates a directory.  In builtin configuration,  the  archive
                   browser is registered with the tar file and its compressed file
                   and the LHa compressed file.  You can  describe  configurations
                   in  the initial configuration file to register launchers except
                   these.
    
                   When the file on  the  cursor  position  has  the  unregistered
                   extension, it will behave as same as VIEW_FILE.  In the archive
                   browser, the registered launcher is available, so that you  can
                   invoke the archive browser recursively.
    
              Switch symbolic link mode
                   In  case  of  the symbolic link file, the file information dis-
                   played in the file column and the status  line  shows  not  the
                   status  of  its  referential  file  but  the status of the link
                   itself.  It switches to show  the  status  of  the  referential
                   file.  (UNIX)
    
                   In  the  mode  of  showing  the status of the referential file,
                   'S'(Symbolic Link) is displayed on the left end of the function
                   line.
    
              Switch file type symbol mode
                   Switch  to  display  the symbol which means the file type after
    
                   In the mode of displaying the file type  symbol,  'T'(Type)  is
                   displayed on the left end of the function line.
    
              Switch dot file display mode
                   Switch  not  to display the file whose filename starts with '.'
                   in the file list.  It is toggle to switch if  display  the  dot
                   file or not.
    
                   In the mode of not displaying the dot file, 'H'(Hidden) is dis-
                   played on the left end of the function line.
    
              Switch file flag display mode
                   Switch to display the file  flag,  which  exists  in  some  OS,
                   instead  of the file mode on each file.  It is toggle to switch
                   if display the file flag or the file mode.  This is not  avail-
                   able  on  any  OS without the file flag.  The each symbol means
                   the following respectively.  (UNIX)
                        A    Archived
                        N    Nodump
                        a    system Append-only
                        c    system unChangeable (immutable)
                        u    system Undeletable
                        a    user Append-only
                        c    user unChangeable (immutable)
                        u    user Undeletable
    
                   In the mode of displaying the file  flag,  'F'(Flags)  is  dis-
                   played on the left end of the function line.
    
              Search file
                   Search  the  current  directory incrementally for the filename,
                   with moving a cursor.  When you execute this command, to switch
                   to the search mode, a prompt appears in the function line.  You
                   can input the filename in this prompt, and a cursor  will  move
                   to  the  filename matching the string which is already inputted
                   at that present.  [Esc] switches to the normal mode.
    
              Split window
                   Split the current window.  When you split a window in the  nor-
                   mal  non-split window mode, it will be the split window mode in
                   which the screen is split into 2 windows  vertically.   In  the
                   split  window  mode, you can operate works individually on each
                   window.  When you split a window in the split window mode,  the
                   current working window is split into 2 windows vertically.  You
                   can make split windows up to 5.
    
              Change window
                   Change effective window to the next in the split  window  mode.
                   When  the  current window is the last, the first window will be
                   effective.  In the non-split window mode, it is ineffective.
    
                   the  previous window.  When the current window is the first, it
                   will be joined to the last window.  If  the  result  number  of
                   windows  is  one, it will be the non-split window mode.  In the
                   non-split window mode, it is ineffective.
    
              Invoke customizer
                   Invoke the customizer which interactively changes the  configu-
                   rations  to  be set up by the internal variable and the builtin
                   command.  While the configurations which  is  set  up  here  is
                   reflected  immediately,  you must intentionally save configura-
                   tions in the customizer if you want to reflect in  the  initial
                   configuration file.

       Commands
           In EXECUTE_SH and the initial  configuration  file,  you  can  use  the
           internal  commands  described  above and the builtin commands described
           below, as well as  the  external  commands.   With  these  commands,  a
           pipeline  can  consist of one or more commands separated by | or |&.  |
           connects the standard output of the previous command  to  the  standard
           input  of  the  next command.  |& connects both the standard output and
           the standard error output of the previous command to the standard input
           of  the next command.  The exit status of a pipeline is the exit status
           of the last command.  You can start a pipeline with !,  then  the  exit
           status  of a pipeline will be the logical NOT of the exit status of the
           last command.  Moreover, a command list can  consist  of  one  or  more
           pipelines  separated  by  ;,  &, &|, &&, ||.  This command list can end
           with ;, & or &|.  These separators mean the following.
              ;    Execute commands sequentially.
              &    Execute commands synchronously, not waiting for  the  preceding
                   pipeline to finish.  (UNIX)
              &|   Same as &, except to immediately disown the job.  (UNIX)
              &&   Execute  the  following pipeline only if the preceding pipeline
                   returns a 0 exit status.
              ||   Execute the following pipeline only if the  preceding  pipeline
                   returns a non-0 exit status.
           In these command lists, a newline means as same as ;.
    
           The  input/output of each command in the command list can be redirected
           with the following redirectees.  These redirectees can be placed on any
           position in the command string.
              n1<&n2    Redirect  the  input  indicated  by the file descriptor n1
                        into the input indicated by the file descriptor n2.  If n1
                        is  omitted,  it  is  regarded  as  the  standard input is
                        specified.
              n1>&n2    Redirect the output indicated by the  file  descriptor  n1
                        into  the  output indicated by the file descriptor n2.  If
                        n1 is omitted, it is regarded as the  standard  output  is
                        specified.
              &>file    Redirect  both  the standard output and the standard error
                        output into the output to file.  If file doesn't exist  it
                        is  created,  otherwise it is truncated to 0 length before
                        output.
              &>|file   Same as &>, except to force to  overwrite  existent  files
                        even if -C option is set by set the builtin command.
              &>>file   Redirect  both  the standard output and the standard error
                        output into the output to file.  If file doesn't exist  it
                        is created, otherwise output is appended to it.
              n<>file   Redirect  both  the  input/output  indicated  by  the file
                        descriptor n into the input/output from/to file.  If n  is
                        omitted,  it  is  regarded as the standard input is speci-
                        fied.
              n><file   Redirect both  the  input/output  indicated  by  the  file
                        descriptor  n into the input/output from/to file.  If n is
                        omitted, it is regarded as the standard output  is  speci-
                        fied.
              n1<>&n2   Redirect  both  the  input/output  indicated  by  the file
                        descriptor n1 into the input/output indicated by the  file
                        descriptor  n2.   If  n1 is omitted, it is regarded as the

              n<<[-]word
                        Redirect the input indicated by the file descriptor n into
                        the input which is read up to a  input  line  as  same  as
    
              accept://[host][:port]
                        This socket is accepted to the  local  host  specified  by
                        host  with the TCP port number specified by port.  If host
                        is omitted, this socket will be accepted to any host.   If
                        port  is  omitted, the port within the range determined by
                        the OS is used.
              bind://[host][:port]
                        This socket is bound to the local host specified  by  host
                        with  the  TCP  port  number  specified by port, preparing
                        accept the builtin command.   If  host  is  omitted,  this
                        socket  will be accepted to any host.  If port is omitted,
                        the port within the range determined by the OS is used.
    
           On each command line, the string from '#' to the end of line and a null
           line  are ignored.  When the line ends with '\', it is referred as con-
           tinuing into the next line, so that you can  split  a  long  line  with
           this.
    
       Builtin Commands
           Fd  has  the following builtin commands.  These builtin commands can be
           used in EXECUTE_SH and the initial configuration file.
    
           if list then [elif list then list] ... [else list] fi
                         The list of if clause and elif clauses  are  executed  in
                         order,  and  if each exit status is a 0, then the list of
                         then clause associated with it is executed and  the  elif
                         clauses  after  it  are ignored.  If no list of if clause
                         nor elif clauses return a 0, the list of else  clause  is
                         executed.   If no list of then clauses nor else clause is
                         executed, then if returns a 0 exit status.
    
           while list do list done
                         The list of while  clause  is  executed  repeatedly,  and
                         while its exit status is 0, the list of do clause is exe-
                         cuted repeatedly.  If the list of do clause is never exe-
                         cuted, then while returns a 0 exit status.
    
           until list do list done
                         The  list  of  until  clause  is executed repeatedly, and
                         while its exit status is NOT 0, the list of do clause  is
                         executed  repeatedly.   If the list of do clause is never
                         executed, then until returns a 0 exit status.
    
           for NAME [in value ...] do list done
                         NAME the internal variable is substituted for  values  of
                         value  one  by one, and list is executed according to the
                         each value.  If in value is omitted, then each positional
                         parameter is substituted one by one.
    
           case word in [pattern [| pattern] ... ) list ;;] ... esac
                         The  string  word is compared with the each pattern, list
                         associated with the pattern which  first  matches  it  is
                         variable.
    
                         If value is omitted, the value of NAME the internal vari-
                         able  is  defined  as  a null.  If you want to delete the
                         definition of a internal variable, use unset the  builtin
                         command.
    
           name() { list; }
                         Define  a  function  whose  body  is list, as the name of
                         name.  The defined function can be used  in  the  command
                         line  of  EXECUTE_SH  and  each  command  macro described
                         below.  You can use the positional parameter $n  in  each
                         description  of  list,  which indicates the argument when
                         the function is invoked.  $0 is name  itself,  and  $1-$9
                         indicates each argument.
    
                         Although  you  cannot omit { } and list, you can omit { }
                         before/after list which consists of a single command.  If
                         you  want  to  delete  the  definition of a function, use
                         unset the builtin command.
    
           !num          Execute the command which has the history  number  speci-
                         fied  with  the  numeric value num.  When num is negative
                         value, it executes the command which has the history num-
                         ber as the current history number minus num.
    
           !!            Execute the previous command.  This is synonym for !-1.
    
           !str          Execute  the command history which starts with the string
                         str.
    
           : [arg ...]   No effect.  But it evaluates arg  and  performs  redirec-
                         tion.
    
           . file
           source file   Read  and  evaluate commands from file.  File must exists
                         on the directory which PATH  includes,  or  be  described
                         with pathname.  The each line format is based on the for-
                         mat of EXECUTE_SH.  You can describe this in the file  as
                         nesting.
    
           accept [fd]   Accept  the connection with the file descriptor indicated
                         by fd, and the connected socket will be assign to  fd  of
                         the same file descriptor.  At the same time, the accepted
                         socket will be closed.  When fd is not the redirection as
                         the  form  of  bind://,  this command will be failed.  In
                         comparison with the redirection as the form of accept://,
                         the  shell  can receive controls before establishing con-
                         nection to negotiate the TCP port number with the  remote
                         host in advance.  (UNIX)
    
                         If  fd  is  omitted, the connection will be accepted with
                         The defined alias can be used in the command line of EXE-
                         CUTE_SH  and  each  command  macro  described below.  The
                         alias substitution is performed recursively.
    
                         If com is omitted, the alias of name  is  displayed.   If
                         both com and name are omitted, all the current alias def-
                         inition list is displayed.
    
           arch ext [pack unpack]
                         Register the archiver command associated with the archive
                         file  which  has  ext the extension.  The pack command is
                         specified as pack, and the unpack command is specified as
                         unpack,  using  the  macro  representation quoted with ".
                         When ext starts with /, uppercase/lowercase is ignored in
                         the comparison of any extension.
    
                         If both pack and unpack are omitted, the archiver command
                         registration for ext the extension is deleted.
    
           bg [job]      Continue the execution of the job specified with  job  in
                         the  background.   The  following  format is available to
                         specify a job.  (UNIX)
                               %
                               %+   the current job
                               %-   the previous job
                               %n   the job with job number n
                               %str the job whose command line starts with str
                         But, you must describe these % in  the  command  line  of
                         EXECUTE_SH  as the duplicated expression, such as %%, for
                         the reason of  the  parameter  macro  function  described
                         below.
    
                         If  job  is  omitted, the current job is continued in the
                         background.
    
           bind c [com1 [com2] [:comment]]
                         Bind the command com1 to the key c.   When  you  want  to
                         specify  a control character for c, you can prefix ^ into
                         2 characters, such as ^A.  When you  want  to  specify  a
                         character  with  the  META  key (or the ALT key on MS-DOS
                         version), you can prefix @ into 2 characters, such as @a.
                         When  you  want  to  specify a function key and a special
                         key, you can use each identifier described in keymap com-
                         mand  after, such as F10.  Or you can describe the escape
                         sequence, such as \n and \e, and  the  octal  expression,
                         such as \ooo.
    
                         In  case  of  binding the internal command of fd, you can
                         the command identifier as it is.  When you want to define
                         the  internal  command  with some arguments or define the
                         command in the macro representation, you should  describe
                         the  string  quoted with ".  If com2 is not omitted, com2
                         so on.  If n is specified, it breaks n  levels  from  the
                         loop.
    
           browse [-@ file]
           browse com [-ftbie arg] [-p com2] [-dn {noprep,loop}] ...
                         Execute  com  the command, and invoke the archive browser
                         who receives its output.  You should the macro  represen-
                         tation  quoted  with  "  as  com.   -f, -t, -b, -i and -e
                         options are the same as the one for  launch  the  builtin
                         command.   In  case that multiple coms are specified, the
                         next com the command is executed one after  another  when
                         you  select  each  files  in the archive browser, and the
                         formats and patterns described after each com the command
                         are adopted.  In order to return to the previous level of
                         archive browser, you should select the file named  as  ..
                         or  push  the  key  [Bs].  Or you can use QUIT_SYSTEM the
                         command to  escape  from  all  of  the  archive  browsers
                         invoked  by  browse.  You must describe -f option, except
                         for the last com the command.  When the last com  has  no
                         -f  option, the command has been just executed instead of
                         invoking an archive browser, and then will return to  the
                         previous archive browser when it is done.
    
                         When  you  specify  -p  option, the execution of com2 the
                         command precedes the execution of the next com  the  com-
                         mand  when  you  select a file.  While com is executed in
                         the sub shell for a pipeline, com2  is  executed  in  the
                         current shell to inherit the values of internal variables
                         set in this command after com2 has been done.  The  file-
                         names  which  is  selected  toward  this level of archive
                         browser are held in positional  parameters  sequentially,
                         and  the  last  selected  filename  is held in $1.  These
                         parameters will be newly set whenever you select a  file,
                         so  that  they  are  reset  in  sequential order when you
                         select the next file even if you replace them with set or
                         shift  the  builtin command.  -d and -n options specify a
                         control if the  selected  file  is  a  directory  or  not
                         respectively.  When you specify noprep, com2 specified by
                         -p option is not executed.  When you  specify  loop,  you
                         don't  step the next com the command but the same com the

                         And when you think troublesome to describe too many argu-
                         ments  for browse, you can specify file the file in which
                         some arguments are described with  -@  option.   You  can
                         describe  -@  option in any place of arguments, the argu-
                         ments described in file are inserted in the  place  where
                         -@ is described.  If you specify - as file, arguments are
                         read from the standard input instead of  the  file.   You
                         should describe arguments in file with spaces or newlines
                         as separator.  The null line and the line started with  #
                         will  be  ignored.   When you describe -@ option in file,
                         If  -L  is specified, the logical pathname following sym-
                         bolic links is used.  If -P is  specified,  the  physical
                         pathname following no symbolic links is used.  Otherwise,
                         the physical option for set the builtin command is effec-
                         tive.
    
           checkid [file ...]
                         Calculate the unique ID of the specified file and display
                         it, according to the MD5 algorithm in RFC1321.  When  you
                         specify  multiple  files,  the IDs of all specified files
                         are calculated and displayed.  When you specify  nothing,
                         the ID of running fd itself is displayed.
    
                         Since  this  algorithm  is guaranteed to be secure, it is
                         available to confirm the identity of files.
    
           cls           Clear the screen.
    
           command [-p | -v | -V] arg ...
                         Execute arg as a simple command.   When  the  same  named
                         function  is  defined, the function will not be executed.
                         If -p is specified, the default value of PATH is used  to
                         search  the  path.  If -v is specified, the absolute path
                         for arg is displayed instead of executing arg.   In  this
                         case, arg the builtin command will cause simply its name.
                         If -V is specified, verbose description for arg  is  dis-
                         played as same as type.
    
           continue n    Resume  the next iteration in the loop, it is used in the
                         for statement and so on.  If n is specified,  it  resumes
                         the  next  iteration  in the loop n - 1 levels out of the
                         loop.
    
           copy [-ABVY-Y] src [-AB] [+ src2 [-AB] [+ ...]] [dest [-AB]]
                         Copy the file indicated by  src  into  the  file  or  the
                         directory  indicated  by  dest.   When  dest  indicates a
                         directory, the filename in the destination  is  src.   If
                         dest is omitted, it is copied into the current directory.
                         You can specify multiple source files  by  describing  to
                         separate them with +, or by using the wildcard.  When you
                         separate them with +, those files  are  concatenated  and
                         copied.   When  you use the wildcard, they are copied one
                         by one in case that the destination is a  directory,  and
                         they  are  concatenated in case that the destination is a
                         file.
    
                         When you specify -A, it is  treated  as  the  ASCII  text
                         file.   When  you specify -B, it is treated as the binary
                         file.  When you specify -V, it is verified to copy.  When
                         you  specify  -Y,  it  doesn't  prompts for confirming to
                         overwrite into the destination.  When you specify --Y, it
                         prompts for confirmation before overwriting into the des-
                         option prefix for compatibility with COMMAND.COM.)
    
           dir [-[-]PWSBLV4] [-A[DRHSA-]] [-O[NSEDGA-]] [dir]
                         List files and sub directories in the directory indicated
                         by  dir.   If dir is omitted, the information in the cur-
                         rent directory is listed.
    
                         When you specify -P, it prompts for every  screen.   When
                         you  specify -W, it is listed in the wide view.  When you
                         specify -A, it  lists  only  the  files  which  have  the
                         attribute indicated by the trailing character.
                               D  directory        R  read only file

                         When  you specify -O, it sorts with the sorted type indi-
                         cated by the trailing character.

                               -  reverse order
                         When you specify -S, it lists files in all  sub  directo-
                         ries.   When  you  specify  -B, it displays only names of
                         files and directories.  When you specify -L, it uses low-
                         ercase.  When you specify -V, it lists the verbose infor-
                         mation.  When you specify -4, it  displays  year  with  4
                         digits.   And  you  can  prefix - to any option letter to
                         override the option.
    
                         (MS-DOS version requires to use /  instead  of  -  as  an
                         option prefix for compatibility with COMMAND.COM.)
    
           dirs          Display  the  list of the current directory stack.  Pushd
                         and popd the builtin command can load/unload  directories
                         onto the directory stack.
    
           disown [job]  Remove the job specified with job from the shell control.
                         The job to be disowned cannot be controlled by  jobs,  fg
                         and  bg.  If invoked as a login shell, any jobs not to be
                         disowned will be forced to exit when  the  shell  finish.
                         (UNIX)
    
                         If  job  is  omitted, the current job is removed from the
                         shell control.
    
           dtype file    Display the contents of the file indicated by file.
    
           echo [-nN] [arg ...]
                         Echo arg to the standard output.  When you don't  specify
                         -n,  newline is added to output trailing after arg.  When
                         you specify  -N,  the  outputted  newline  becomes  CR-NL
                         (\r\n).  See echo(1) for details.
    
    
           exec [com [arg ...]]
                         Execute  com  in  place  of the execution of fd.  You can
                         specify arg as arguments of com.
    
           exit [n]      Exit from fd.  When you specify n, it exits with the exit
                         status n.
    
           export [NAME[=[value]] ...]
                         Mark  NAME the internal variable to be inherited to child
                         processes as the environment variable.  Since  then,  the
                         definition  of NAME can be referred in any child process.
                         When you  export  the  undefined  internal  variable,  it
                         doesn't  become the environment variable until the inter-
                         nal variable is defined.  When you  want  to  define  the
                         value at the same time, you should specify value.
    
                         If only = is specified and value is omitted, the value of
                         NAME the environment variable is defined as a  null.   If
                         no argument is specified, all of the exported environment
                         variables is listed.  When you want to delete the defini-
                         tion  of  the environment variable, you can use unset the
                         builtin command.
    
           false         Only return with a 1 exit status.
    
           fc [-l | -s [old=new ...]] [-nr ] [-e editor] [first [last]]
                         List or edit command histories.  First  and  last  select
                         the  range  of command histories.  This specification can
                         be described as a numeric value or a string.  A  positive
                         value  means  the  command history number, and a negative
                         value means the command history  which  has  the  history
                         number  as the current history number minus the value.  A
                         string mean the command history  which  starts  with  the
                         string.  If -n is specified, command histories are listed
                         without their history numbers.  If -r is specified,  com-
                         mand  histories  are  listed  in reverse order.  If -e is
                         specified, the editor named by editor  is  used  to  edit
                         command  histories,  otherwise  the  editor  specified by
                         FCEDIT or EDITOR the internal variable is used.
    
                         When -l is  specified,  selected  command  histories  are
                         listed  to  the  standard output.  In this case, omitting
                         last means to specify the  current  history  number,  and
                         also omitting first means to specify -16.
    
                         When  -s  is  specified,  the command history selected by
                         first is executed immediately.  In  this  case,  omitting
                         first  means  to specify the current history number.  The
                         first occurrence of the string old in the command history
                         will be replaced by the string new before execution.
    
                         only when it is invoked as fdsh.
    
           fg [job]      Continue the execution of the job specified with  job  in
                         the  foreground.   The  following  format is available to
                         specify a job.  (UNIX)
                               %
                               %+   the current job
                               %-   the previous job
                               %n   the job with job number n
                               %str the job whose command line starts with str
                         But, you must describe these % in  the  command  line  of
                         EXECUTE_SH  as the duplicated expression, such as %%, for
                         the reason of  the  parameter  macro  function  described
                         below.
    
                         If  job  is  omitted, the current job is continued in the
                         foreground.
    
           getkey [num]  Get the key code sequence for the pushed key.  It prompts
                         after  executed,  and  displays the key code sequence for
                         the key which you push to specify.   It  continues  until
                         you  push  any  key  num  times.  When num is more than 1
                         time, you can stop it with pushing [Space].  When num  is
                         0  time,  it  continues  forever until [Space] is pushed.
                         The displayed sequence  can  be  used  as  the  key  code
                         sequence for keymap command.  (UNIX)
    
                         If num is omitted, it is regarded as 1 time is specified.
    
           getopts optstr NAME [arg ...]
                         Used to parse the optional parameters from a sequence  of
                         arg.  The valid characters as option is described in opt-
                         str.  An option character  which  needs  an  argument  is
                         described  with following : in optstr.  Each time getopts
                         is invoked, the new option character parsed from  arg  is
                         substituted  for  NAME  the  internal variable.  When the
                         option has an argument, the argument is  substituted  for
                         OPTARG  the internal variable.  And the index of the next
                         parameter is substituted for OPTIND the internal variable
                         every  time.   The  value  of  OPTIND is initialized to 1
                         whenever the shell is invoked, another parsing of  option
                         parameters  needs  initializing OPTIND to 1 manually.  If
                         arg is omitted, positional parameters are parsed  to  the
                         optional parameters.
    
                         When  the end of option is encountered, getopts will exit
                         with the value of 1.  In this case, ?  is substituted for
                         NAME.   When an option character which is not included in
                         optstr is found, an error message is written to the stan-
                         dard error, then ?  is substituted for NAME and OPTARG is
                         unset.  But, if OPTARG is started with :, no  error  mes-
                         sage  is  written, and the found option character is sub-

                         ble information is listed.  hits, cost, command  indicate
                         the  number  of  times the command has been executed, the
                         measure of the work required to search it in  the  search
                         path,  and  the  absolute  path  for the command, respec-
                         tively.  When the  command  is  searched  in  a  relative
                         directory, it is necessary to re-search whenever the cur-
                         rent directory is moved, because it is not registered  as
                         the  absolute  path.  In such command, * trailing hits is
                         displayed.
    
           history [n]   List the last n command histories with the  history  num-
                         ber.
    
                         If  n  is omitted, all of the memorized command histories
                         is listed.

           kconv [-i in] [-o out] [infile [outfile]]
                         Read from infile and convert its Kanji code  from  in  to
                         out, and output to outfile.  In in and out, you can spec-
                         ify the string which  used  in  FNAMEKCODE  the  internal
                         variable described below.  If each of them is omitted, it
                         is regarded as that the Kanji code specified  in  compile
                         is  specified.   If outfile is omitted, it outputs to the
                         standard output.  If also infile  is  omitted,  it  reads
                         from the standard input.  (UNIX)

                         You can use the escape sequence in the key code sequence,
                         such  as  \n  =0x0a  and  \e =0x1b.  You can also use the
                         octal expression, such as \ooo.   You  can  describe  the
                         control  character prefixing ^, such as ^A.  ^ itself can
                         -l, it lists the signal names which can be used as signal
                         instead of sending a signal.
    
           launch ext [com [format [top bottom]]]
           launch ext com [-f format] [-t top] [-b bottom] [-ie patt]
                         Register the  behavior  for  ext  the  extension  as  the
                         launcher.   You  should  the  macro representation quoted
                         with " as com.  When you register an archive browser, you
                         should describe the command to list the archived files as
                         com, and describe the format of the list as format.  When
                         you  describe top and bottom, you can specify unnecessary
                         lines in the  list  as  the  number  of  lines  from  the
                         top/bottom  line.  When ext starts with /, uppercase/low-
                         ercase is ignored in the comparison of any extension.
    
                         If com is omitted, the launcher registration for  ext  is
                         canceled.
    
                         When  you  register  an  archive browser, you can use the
                         latter form to describe more detailed control.   You  can
                         specify  multiple  formats as candidates with multiple -f
                         options.  These candidates for  format  are  compared  in
                         order of appearance, if no one is matched completely then
                         the nearest one is adopted.  -i and  -e  options  specify
                         patt  the  pattern for the line to be ignored and for the
                         line to be treated as error respectively.  When the  list
                         includes  unnecessary  lines you can specify also top and
                         bottom, but you  must  specify  lines  except  top/bottom
                         lines  with  -i option.  In case that a failure to unpack
                         files in the archive file causes outputting some strings,
                         you  can  specify  the strings with -e option.  -i and -e
                         options can  specify  multiple  patterns,  and  they  are
                         effective  if  one of them is matched.  And you can use a
                         wildcard in the description for each patt the pattern.
    
           md dir        Create the directory dir.
    
           mkdir dir     Same as md.  (DOS)
    
           newgrp [arg ...]
                         Execute newgrp(1) in place of the execution of  fd.   You
                         can specify arg as arguments of newgrp(1).  See newgrp(1)
                         for details.  (UNIX)
    
           login [arg ...]
                         Execute login(1) in place of the execution  of  fd.   You
                         can  specify  arg as arguments of login(1).  See login(1)
                         for details.  (UNIX)
    
           logout [n]    Exit from a login shell.  When you specify  n,  it  exits
                         with the exit status n.
    
                         If  c  is  omitted, all of the registered key bindings is
                         listed, which is defined not as the internal command  but
                         as  the command macro.  The key bindings of internal com-
                         mands can be referred in HELP_MESSAGE.
    
           printdrv [c]  Print the  device  file  and  the  number  of  heads/sec-
                         tors/cylinders  of  the  floppy  drive registered for the
                         drive name c.  (UNIX)
    
                         If c is omitted, all of the registered floppy  drives  is
                         listed.
    
           printlaunch [ext]
                         Print  the  command  macro registered as the launcher for
                         ext the extension.  When it is registered as the  archive
                         browser, the format for listing is also printed.
    
                         If  ext  is  omitted,  all of the registered launchers is
                         listed.
    
           printroman [roman]
                         Print the Roman-Kana translation table for the Kana-Kanji
                         IME  mode.   It  means printing the Japanese string bound
                         for roman the Roman string.  (UNIX)
    
                         If roman is omitted, all the registered Roman-Kana trans-
                         lation table is listed.
    
           pushd [dir]   Load  the current directory onto the directory stack, and
                         change the current directory in fd to dir.  If you  spec-
                         ify  the  pathname as ".", "?", "-", "@", it behaves like
                         as LOG_DIR.  The physical option for set the builtin com-
                         mand is effective for symbolic links.
    
                         If  dir  is  omitted, change the current directory to the
                         top directory of the directory stack, and replace it with
                         the  current  directory.   In  this case, this command is
                         failed when the directory stack is empty.
    
           pwd [-LP]     Display the current directory with the absolute represen-
                         tation.  If -L is specified, the logical pathname follow-
                         ing symbolic links is displayed.  If -P is specified, the
                         physical  pathname  following  no  symbolic links is dis-
                         played.  Otherwise,  the  physical  option  for  set  the
                         builtin command is effective.
    
           read [-N] [NAME ...]
                         Read one line from the standard input and substitute that
                         string for NAME  the  internal  variable.   The  inputted
                         string  is separated with IFS into some words.  When mul-
                         tiple NAMEs are specified, words are substituted  one  by
                         one  from the first of line, and all the rest are substi-
                         pletion for a pathname.
    
           readonly [NAME[=[value]] ...]
                         Mark  NAME  the  internal variable to be readonly.  Since
                         then, you cannot change the value of NAME.  When you want
                         to  define the value at the same time, you should specify
                         value.
    
                         If only = is specified and value is omitted, the value of
                         NAME  the  internal variable is defined as a null.  If no
                         argument is specified, all of the readonly internal vari-
                         ables is listed.
    
           rd dir        Delete  the  directory  dir.   You cannot delete the non-
                         empty directory.
    
           rmdir dir     Same as rd.  (DOS)
    
           ren old new
           rename old new
                         Rename the filename or the directory name old  into  new.
                         You can specify the wildcard in old and new to rename the
                         multiple filenames all together.
    
           rem [arg ...] No effect, same as :.
    
           return [n]    Return from a function with the return value specified by
                         n.   If n is omitted, the return value is the exit status
                         of the last executed command.  It cannot be used out of a
                         function.
    
           savetty [-n]  Save  the  current terminal settings.  The saved settings
                         will be restored when EXECUTE_SH is executed  later.   In
                         case  that  you change terminal settings with stty(1) and
                         so on, you should save the settings with this command not
                         to  reset settings with the next execution of EXECUTE_SH.
                         If you change terminal settings and execute this  command
                         not in the same command line, you should notice that this
                         command will save the reset settings.  If  -n  is  speci-
                         fied, the saved settings will be cleared.  (UNIX)
    
           set [--abCefhkmntuvx] [-o option] [arg ...]
                         List  internal variables and functions, without any argu-
                         ment.  When you specify arg, arg is substituted  for  the
                         positional  parameter $1, $2, ..., $n in order.  When you
                         specify any option,  each  option  means  the  following.
                         When  you  use + instead of -, the option parameter turns
                         off each option.
                         -a   Export any internal variable automatically  when  it
                              is defined.
                         -b   When  a background job has been terminated, its sta-

                         -n   Read command inputs but don't execute them.
                         -o option
                              The following identifiers are valid in option.

                         Specify  the  device file indicated by device for the MS-
                         DOS floppy drive named as c.  At the same time,  hd,  sc,
                         cl  are  specified  as  the  number  of heads(sides)/sec-
                         tors/cylinders(tracks) in the format which is treated  in
                         the  driver of device.  In special case, when you want to
                         treat the 640KB2DD(hd=2/sc=8/cl=80) floppy disk with  the
                         driver which can treat only the 820KB2DD(hd=2/sc=9/cl=80)
                         floppy disk, you should  specify  the  value  adding  100
                         (108) as the value of sc.  (UNIX)
    
                         On  the PC-UNIX environment which is worked on PC, speci-
                         fying the string HDD or HDD98 instead of hd, sc, cl,  can
                         register  the  MS-DOS  partition on the hard disk for the
                         PC/AT compatible machine  or  PC-9800  series.   In  this
                         case,  You  should describe the device file as the device
                         name prepared per the physical drive unit rather than the
                         device  name prepared per the partition (slice).  The MS-
                         DOS partitions included in the drive unit  are  automati-
                         cally  expanded to the drive name after the drive name c.
                         When no MS-DOS partition is  included  in  the  specified
                         drive  unit,  this  command  is ignored.  You can confirm
                         what drive name is valid by printdrv  command.   But  any
                         hard disk is registered as readonly, for security.
    
           setroman [-c] [-r] [-f file] [roman [kanji]]
                         Setup the Roman-Kana translation table for the Kana-Kanji
                         IME mode.  It means binding kanji the Japanese string  to
                         roman  the  Roman  string.  The part over 4 characters of
                         roman, the string which consists  of  1  byte  characters
                         only,  will  be  ignored.   The part over 2 characters of
                         kanji, the string which consists of multibyte  characters
                         or  1  byte characters, will be ignored.  In this case, a
                         multibyte character is counted as 1 character as well  as
                         a 1 byte character.  (UNIX)
    
                         If kanji is omitted, the registered binding of the Roman-
                         Kana translation table for roman the Roman string will be
                         deleted.   When  you  specify  -c,  the  whole Roman-Kana
                         translation table will be cleared to be empty.  When  you
                         specify  -r, all the registered bindings will be reset to
                         restore the Roman-Kana translation table.  When you spec-
                         ify  -f, the file specified by file will be read as bind-
                         ings of the Roman-Kana translation table.  In this  case,
                         a  pair of roman and kanji, which is separated by spaces,
                         must be described in each line of file.  You can also use
                         the file which contains the output of printroman.
                         If fd is omitted, it is regarded as the standard input is
                         specified.  If -a is specified, only the  IP  address  of
                         the  remote  host will be outputted.  If -p is specified,
                         only the TCP port number of the remote host will be  out-
                         putted.   If  -A is specified, only the IP address of the
                         local host will be outputted.  If -P is  specified,  only
                         the  TCP port number of the local host will be outputted.

                         reset.  When you  specify  com  as  a  null,  the  signal
                         ignored.   When  you  specify  n as 0, the command com is
                         executed on exit.  If both com and n are omitted, all  of
                         the registered traps is listed.

           ulimit [-SH] [-a | -cdflmnstv] n
                         Set the resource limits for fd and its child processes to
                         the  value indicated by n.  You can use the string unlim-
                         ited or the numeric value in n, unlimited means the maxi-
                         mum specifiable value.  (UNIX)

                         ify -S, a soft limit is set.  When you don't specify nei-
                         ther  of them, both limits are set.  If n is omitted, the
                         current limit is displayed.  When you specify -a, all  of
                         the resource limits is displayed.
    
                         When you specify the following options, the each resource

           expanded automatically when a cursor is placed on its position.
    
           The sub directories which are not expanded yet are represented with '>'
           trailing  the  filename,  which  shows  as they are.  Such directory is
           never expanded until it is required  to  expand  explicitly,  then  you
           should  expand it by the following key inputs before moving to any hid-
           den sub directory.
    
           In the tree screen, the following key inputs are available.
                  Up, Down  Move a cursor.
                  Right     Expand the sub directory on the cursor position.
                  Tab       Expand the sub directory on the cursor position recur-
                            sively.

                  ?         Move a cursor to the current directory.
                  Bs        Move a cursor to the parent directory.
                  Left      Group  sub  directories of the directory on the cursor
                            position, or move a cursor to the parent directory.
                  (, )      Move a cursor to the previous/next directory among the
                            same level sub directories.
                  A - Z     Move  a cursor to the directory whose name starts with
                            the character or its lowercase.
                  l         Change the directory tree into  the  specified  direc-
                            tory.  Moving to the floppy drive is also available.

                  Return    Select the directory.
                  Esc       Cancel.
    
           When  directories are recursively expanded, the machine operation is so
           late that it maybe seems to freeze.  In this case, you  can  input  any
           key while operating.  If key input is recognized while expanding direc-
           tories, expanding has been stopped at that moment in spite of not  fin-
           ishing.   Even  if  key  repeat  keeps effective, any operation will be
           delayed for this function.
    
       Archive Browser
           When the launcher is invoked on the position of the file  whose  exten-
           sion  is  registered  to associate with an archive browser, the archive
           browser screen has come.  In this screen, you can browse files  in  the
           archive  file  as  well as in the normal directory.  But you cannot use
           the following internal commands in this screen.
                  LOG_TOP        ATTR_FILE      COPY_FILE      MOVE_FILE
                  DELETE_FILE    DELETE_DIR     RENAME_FILE    MAKE_DIR
                  WRITE_DIR      TREE_DIR       EDIT_FILE      LOG_TREE
                  COPY_TREE      MOVE_TREE      FIND_DIR       ATTR_DIR
                  SYMLINK_MODE   DOTFILE_MODE   FILEFLG_MODE   SPLIT_WINDOW
    
           When you want to register a new archive browser, you must describe  the
                  %B        Field which indicates a major device ID
                  %b        Field which indicates a minor device ID
                  %/str/    Field which indicates a type is directory
                            when this field string is str
                            (case insensitive)
                  %!str!    0 or more continuous fields
                            which consists of the string str
                            (case insensitive)
                  %f        Field which indicates a filename
                  %x        Field which is needless (ignored)
                  %%        % itself
                  \n        Newline
                  Space Tab 0 or more characters of spaces or tabs
    
           In this description, the field means the area separated by spaces, tabs
           or newlines.  When the string which indicates each information is sepa-
           rated by these characters, you can simply  describe  the  above  string
           which  indicates  that  field.  When the string is separated by another
           character, you should describe the above string  with  that  separator.
           You can describe to indicate the field length as numeric, such as %10a.
           This example means that the field which indicates a file mode  consists
           of  10  characters.  If you describe it with a character * as the field
           length instead of numeric, such as %*f, the string to the end  of  line
           is regarded as a field, in which any space and tab will be ignored.
    
           When  a  field  may have the different meanings according to situation,
           you should describe it quoted with { }, such as  %{yt}.   This  example
           means  that  this  field  indicates a creation year or a creation time.
           When the information for 1 file consists of multiple lines, you  should
           place a \n on the position of newline in the format string.
    
           For  example, the following are the format strings for the list of some
           archivers.  While some spaces are used here for easiness to see,  these
           spaces  are  not  always  necessary because any space between fields is
           ignored.
           'lha l'           "%9a %u/%g %s %x %m %d %{yt} %f"
           'lha v' (MS-DOS)  "%f\n%s %x %x %y-%m-%d %t"
           'tar tvf' (BSD)   "%9a %u/%g %s %m %d %t %y %f"
           'tar tvf' (SVR4)  "%a %u/%g %s %m %d %t %y %f"
    
           If you register archive browsers with above format, in the builtin com-
           mand  of  EXECUTE_SH  or in the initial configuration file, you can use
           the archive browser which is not prepared by default.  But, if you want
           to  execute  or  view  files in the archive file, you must register the
           archiver command for the archive file, too, don't forget this.
    
           On some OS, tar(1) may output the Japanese timestamp when  japanese  is
           substituted for LANG the environment variable.  Since fd cannot analyze
           the representation like this, you should describe  'export  LANG=C'  in
           the  initial  configuration file, or specify LANG in the description of
           listing command, such as 'LANG=C tar tvf'.
    
           Each  drive of the floppy drive has the its own current directory.  The
           default value of this is a root directory, and the current directory is
           moved back to a root directory again whenever you change a floppy disk.
           When you describe the directory name as starting with '/' after ':', it
           means  the  absolute path representation of that drive.  If this '/' is
           not exist, it means the relative path representation from  the  current
           directory of that drive, don't forget this.
    
           Regrettably,  some  internal  commands  like as WRITE_DIR, INFO_FILESYS
           cannot support the floppy drive.  Some filenames are renamed when  they
           are copied from UNIX for reason of the filename length limit.
    
           When you use a lowercase letter as the drive name, you can access it as
           the floppy drive which can treat the Long File Name (LFN)  for  MS-Win-
           dows  formatted  floppy disk.  In this case, you can copy a file with a
           long filename on UNIX as it is.  But, when the UNICODE translation  ta-
           ble fd-unicd.tbl does not exist in the same directory as the invoked fd
           exists, any Kanji filename cannot be  treated  as  LFN  representation.
           Reversely,  when  you  use a uppercase letter as the drive name, LFN is
           ignored and 8+3 formed filename is treated.   MS-DOS  version  inherits
           this specification by the case of a drive name.
    
       URL Drive (UNIX)
           You  can access remote services on the network, by representing the URL
           string as the directory name.  The URL format is  scheme://[user[:pass-
           word]@]host[:port]/directory/.   You can specify ftp or http as scheme.
           You can specify the name or IP address of the remote host as host.  You
           can  specify  the  TCP  port  number  as port.  If port is omitted, the
           default port number is used.  The default port number for  ftp  is  21,
           and  the  default  port number for http is 80.  You can specify account
           information to connect the remote host as user and password.   If  user
           is  omitted, the anonymous FTP connection will be used with ftp, or you
           will be queried as needed with http.  If password is omitted, you  will
           be  queried as needed.  But, it is necessary to set URLDRIVE the inter-
           nal variable which makes this function effective, in advance.
    
           Regrettably, some internal commands cannot support the URL  drive,  for
           the  sake  of restrictions of the FTP and HTTP protocols or settings of
           the host side.
    
       String Input
           When you input the string, such as  the  pathname,  the  following  key
           inputs  are  available.   The kind of referred history differs with the
           input string required.  In the split window mode, the current directory
           of  another window is always placed on the top of the pathname history.
           Left, Right
                     Move a cursor.
           Up, Down  Refer the previous histories (only commands  and  pathnames),
                     or move a cursor.
           Beg       Move a cursor to the beginning of string.
           Eol       Move a cursor to the end of string.
           Ins       Switch a input method to the insert/overwrite mode.  (Default
                     from this list with cursor keys and [Return].
           ^L        Redraw the input string.
           ^S, ^R    Search  the  previous histories (only commands and pathnames)
                     incrementally.
           Return    Decide the input, or decide  the  choice  in  the  completion
                     choice list.
           Esc       Cancel.
    
           The  inputted string is expanded before evaluation as following.  These
           expansions are also valid in the string of command macros.   But  these
           expansions  are restrained in the string quoted with the quotation mark
           '.
    
           ~       Indicate your home directory, when it is the beginning of file-
                   name.
    
           ~user   Indicate  user's  home  directory,  when it is the beginning of
                   filename.  (UNIX)
    
           ~FD     Indicate the directory where the invoked fd is exists, when  it
                   is the beginning of filename.
    
           $NAME
           ${NAME} Indicate  the  value of NAME the internal variable or the envi-
                   ronment variable.  When both are defined, the internal variable
                   is prior.  When both are undefined, it is replaced a null.  The
                   brace { } separates NAME from its trailing characters.
    
                   When NAME is the following character, it  is  replaced  by  the
                   value substituted automatically by the shell.
                   0      The executable filename when invoked.
                   [1-9]  The positional parameter.
                   *      The  all  positional  parameters  which  starts from $1.
                          "$*" is replaced by "$1 $2 ...".
                   @      The all positional  parameters  which  starts  from  $1.
                          "$@" is replaced by "$1" "$2" ... .
                   #      The number of positional parameters.
                   -      The option flags which is set by options when invoked or
                          set the builtin command.
                   ?      The exit status of the last executed command.
                   $      The process number of the current shell.
                   !      The process number of the last executed background  pro-
                          cess.
    
           ${NAME:-word}
                   If the value except a null is substituted for NAME the internal
                   variable or the environment variable, it  is  replaced  by  the
                   value, otherwise it is replaced by word.
    
           ${NAME:=word}
                   If the value except a null is substituted for NAME the internal
                   variable or the environment variable, it  is  replaced  by  the
                   otherwise it is replaced by a null.
    
           ${NAME-word}
                   If  any  value is substituted for NAME the internal variable or
                   the environment variable, it is replaced by the  value,  other-
                   wise it is replaced by word.
    
           ${NAME=word}
                   If  any  value is substituted for NAME the internal variable or
                   the environment variable, it is replaced by the  value,  other-
                   wise  word  is  substituted for NAME the internal variable, and
                   this expression itself is replaces by  word.   But  you  cannot
                   substitute the value for any positional parameter.
    
           ${NAME?word}
                   If  any  value is substituted for NAME the internal variable or
                   the environment variable, it is replaced by the  value,  other-
                   wise display word and exit from the shell.  If word is omitted,
                   the string ''parameter null or not set'' is  displayed  in  its
                   place.
    
           ${NAME+word}
                   If  any  value is substituted for NAME the internal variable or
                   the environment variable, it is replaced by word, otherwise  it
                   is replaced by a null.
    
           ${#NAME}
                   It is replaced by the length in characters of the value of NAME
                   the internal variable or the environment variable.  If NAME  is
                   *  or  @, it is replaced by the number of positional parameters
                   instead of the length of characters.
    
           ${NAME%word}
                   It is replaced by the string in which the smallest  portion  of
                   the  suffix  matched  by  the  word pattern is deleted from the
                   value of NAME the internal variable or  the  environment  vari-
                   able.   If  NAME  is  *  or  @,  each  positional  parameter is
                   replaced.  ( \ is used instead of % on MS-DOS version.)
    
           ${NAME%%word}
                   It is replaced by the string in which the  largest  portion  of
                   the  suffix  matched  by  the  word pattern is deleted from the
                   value of NAME the internal variable or  the  environment  vari-
                   able.   If  NAME  is  *  or  @,  each  positional  parameter is
                   replaced.  ( \\ is used instead of %% on MS-DOS version.)
    
           ${NAME#word}
                   It is replaced by the string in which the smallest  portion  of
                   the  prefix  matched  by  the  word pattern is deleted from the
                   value of NAME the internal variable or  the  environment  vari-
                   able.   If  NAME  is  *  or  @,  each  positional  parameter is
                   replaced.
    
           The  following  is replaced only in the shell which is executed by EXE-
           CUTE_SH and EXECUTE_FILE.
    
           'list'  List is executed and this string is replaced  by  its  standard
                   output.
    
           $(list) List  is  executed  and this string is replaced by its standard
                   output like as 'list'.  This differs from 'list' in  the  point
                   that  nested  expressions are allowed.  And any meta-characters
                   such as quotes in list are evaluated as it is.
    
           $((expression))
                   Expression the arithmetic  expression  is  evaluated  and  this
                   string  is  replaced  by  its  result  value.   You can specify
                   numeric values, variables and integral  calculations  with  the
                   following operators in expression.
                                         (unary) (binary)
                       arithmetic        + -     + - * / %
                       boolean           !       == != < > <= >= && ||
                       bit operator      ~       & | ^ << >>
                       parenthesis       ( )
    
           ?
           *
           [
           ]       The  string  including  these  letters  is pattern-matched with
                   existent files.  When it is matched, it is replaced by  all  of
                   the matched filenames which are sorted in alphabetical order.
                   ?    Match any single character except /.
                   *    Match any 0 or more length string not including /.
                   **   Match any 0 or more length string including /.
                   [...]
                        Match  any  one  of  the characters enclosed by [ ].  When
                        enclosed characters include -, it  matches  any  character
                        whose character code is between characters before/after -.
                   [!...]
                        Match any one of the characters not enclosed by [ ].
    
                   But, when the first character of the filename is ., ?, * and **
                   don't match it.
    
       Edit Mode
           When  you  want  to use some functions bound to special keys, such as a
           cursor key or a scroll key, such a key doesn't exist in some terminals.
           In such a case, substituting the string for EDITMODE the internal vari-
           able can make you use some control keys as alternative to these special
           keys.   Since this alternative key function is prior to the key binding
           by the builtin command, the key binding  is  invalid  for  the  control
           characters  used  as the alternative keys.  The prepared edit modes are
           the following 3 modes.
    
                       ^C   = PageDn  ^R   = PageUp  ^N   = Enter
                       ^M   = Return  ^I   = Tab     ^H   = Bs
                       ^[   = Esc
    
           vi      Vi mode has the 2  local  modes:  "insert  mode"  and  "command
                   mode",  and  the function of keys are quite different with each
                   mode.  You are in the command mode when  you  start  to  input,
                   then  you  must  input any key among 4 keys which switch to the
                   insert mode, in order to input normal keys.
                       (command mode)
                       k    = Up      0    = Beg
                       j    = Down    $    = Eol     x    = Del
                       l    = Right   g    = Home
                       h    = Left    G    = End     D    = DelLine
                       ^F   = PageDn  ^B   = PageUp  o    = Enter
                       ^M   = Return  ^I   = Tab     ^H   = Bs
                       ^[   = Esc
                       (from command mode to insert mode)
                       i, : = only switch its mode
                                      I    = + Beg
                       a    = + Right A    = + Eol
                       R    = overwrite
                       r    = overwrite once
                       (insert mode)
                       ^V   = InsLine Esc  = to command mode
    
                   This key binding is so particular that it is not  suitable  for
                   those who don't use vi editor everyday.
    
       Kana-Kanji IME (UNIX)
           You  can input strings in the Kana-Kanji IME mode, if you input the key
           specified by IMEKEY or select "Kanji" from the pseudo terminal menu.
    
           The translation performance will depend on the  Kana-Kanji  translation
           dictionary  fd-dict.tbl.   When it does not exist in the same directory
           as the invoked fd exists, translation to Kanji will not  be  available.
           The  standard  installed  dictionary  file is the Tan-Kanji dictionary,
           which can support only the Tan-Kanji translation.  The dictionaly  such
           as the pubdic, which includes the Hinsi information, will bring you the
           Tan-Bunsetsu translation.  The Ren-Bunsetsu translation is not be  sup-
           ported.
    
           In the Kana-Kanji IME mode, the following key inputs are available.
                  Space     Trancelate  to  Kanji,  or select the next translation
                            candidate.
                  Left, Right
                  Up, Down  Move a cursor in the list of  the  translation  candi-
                            date.
                  Bs, Del   Delete a character before the cursor position.
                  Tab       Toggle Hiragana, Katakana, Hankaku-Kana and the direct
                            input.
                  ^L        Redraw the input string.
    
           will be desplayed to select Kanji whose reading starts with the Kana.
    
       Parameter Macros
           You  can use the following parameter macros in the string which is used
           for the registration of command macros and for executing command.  But,
           you  cannot  use  them in the functions, the input file for source com-
           mand, and the initial configuration file, then you should use evalmacro
           command when you want to use any parameter macro in them.
    
           %C      The  filename  on  the  cursor  position.  Or, it indicates the
                   archive filename, in the macro to register  the  archiver  com-
                   mand.
    
           %X      The  filename except its extension on the cursor position.  Or,
                   it indicates the archive filename except its extension, in  the
                   macro  to  register  the  archiver  command.  Only the last one
                   extension is removed.  T, TA, M trailing %X are replaced by %T,
                   %TA,  %M except its extension respectively.  On MS-DOS version,
                   you can describe a trailing S as well as them.
    
           %P      The pathname of the current directory.
    
           %K      Prompt and return to fd after a command is finished.  But,  the
                   meaning  of  %K  is  reverse in EXECUTE_FILE and EXECUTE_SH; it
                   prompts by default and doesn't prompt if %K is specified.   You
                   can  never  specify to prompt in macros to register the archive
                   browser of the launcher and macros  to  register  the  archiver
                   command.
    
           %T      List  marked files separated by spaces as possible.  When files
                   are so many that the command line exceeds 1023 characters,  the
                   rest of marked files are ignored.
    
           %TA     List  marked  files  as well as %T, and repeat the same command
                   for spilt files to complete all marked files.
    
           %M      Execute the same command as many times as marked files, sending
                   the  marked  file  one  by  one.  It is useful to mark files by
                   MARK_FIND and execute "mv %M %XM.bak" by EXECUTE_SH.
    
           %N      Restrain the filename addition even if the parameter  is  omit-
                   ted.
    
           %R      Make  you  input the additional parameter in executing a macro,
                   if the length of command string has enough margin.  The  cursor
                   position  in  input is placed on the position of %R in a macro.
                   But, %R is ignored in macros to register the archive browser of
                   the launcher, macros to register the archiver command, and EXE-
                   CUTE_FILE, EXECUTE_SH.
    
           %S      The 8+3 formed filename with which the LFN formed  filename  on
                   the  cursor  position is replaced.  You can use it when you use
    
           %JJ     The  Kanji  code  of  the string enclosed by this macro is con-
                   verted into ISO-2022-JP.  (UNIX)
    
           %JH     The Kanji code of the string enclosed by  this  macro  is  con-
                   verted into HEX.  (UNIX)
    
           %JC     The  Kanji  code  of  the string enclosed by this macro is con-
                   verted into CAP.  (UNIX)
    
           %JU     The Kanji code of the string enclosed by  this  macro  is  con-
                   verted into UTF-8.  (UNIX)
    
           %JM     The  Kanji  code  of  the string enclosed by this macro is con-
                   verted into UTF-8 for Mac OS X.  (UNIX)
    
           %JI     The Kanji code of the string enclosed by  this  macro  is  con-
                   verted  into  UTF-8  for  iconv,  which is used on environments
                   using iconv-based UTF-8 such as Linux.  (UNIX)
    
           %JA     The Kanji code of the string enclosed by  this  macro  is  con-
                   verted  into the Kanji code which is used in the pathname indi-
                   cated by the string.  The variables SJISPATH, EUCPATH, etc. can
                   specify what kanji code is used in each pathname.  (UNIX)
    
           When no filename parameter, such as %C and %T, is taken with the result
           to expand parameter macros in a command macro, the filename on the cur-
           sor  position is automatically added to the last of expanded string, as
           ./filename form.  This addition is not  done,  in  case  of  the  input
           string for executing command, or when %N macro is specified.
    
       Customize
           You  can  customize fd as the following ways.  If you specify some con-
           figuration in multiple ways overlapped, it is prior in this order.
    
              Executing builtin commands with EXECUTE_SH
                        You can execute builtin commands for each registration for
                        the internal variable definition, the environment variable
                        definition, the alias definition, the function definition,
                        the  key binding, the keymap changing, the launcher regis-
                        tration, the archiver command registration, and the floppy
                        drive registration.
    
              Customizer
                        EDIT_CONFIG command is available for the internal variable
                        definition, the key  binding,  the  keymap  changing,  the
                        launcher  registration, the archiver command registration,
                        and the floppy drive registration.
    
              Command line options
                        You can specify the command line options as  '-NAME=value'
                        form, to define the internal variables.
                        (On MS-DOS  version,  these  filenames  are  $HOME\fd2.rc,
                        $HOME\fdsh.rc and ~FD\fd2rc.)
    
              Environment variables
                        Any  valid  variable  name as the internal variable can be
                        valid  to  be  defined  as  the  environment  variable  in
                        advance.  But the internal variable is always prior to the
                        environment variable in fd.  When the same named  environ-
                        ment variable is used in another application, you can also
                        use the name which FD_ is  prefixed  to  each  environment
                        variable  for fd only.  This environment variable with FD_
                        is always prior to the environment  variable  without  it,
                        then  the  definition of the environment variable with FD_
                        is prior to the definition of the internal variable  with-
                        out FD_.
    
       Customizer
           EDIT_CONFIG  command  invokes  the  customizer to set up configurations
           interactively.  You can select the category with the right/left  cursor
           key,  and  select  the item with the up/down cursor key, and change its
           content with [Return].  When you finish to change, exit from  the  cus-
           tomizer with [Esc].
    
           The following categories are prepared.
              Variables Change  the value of internal variables.  The input method
                        is different with the variable, then you should input fol-
                        lowing the guidance on screen.
              Key bind  Change the command bound to each key.  When you newly bind
                        a command to the key with no binding,  you  should  select
                        "NewEntry".  If you select "Delete bind", the existent key
                        binding is deleted.
              Key map   Change the key code mapping for each special key.  If  you
                        push  [Esc]  when  you  are  prompted to push the key, the
                        existent key mapping is deleted.  (UNIX)
              Launcher  Change the launcher registration for each extension.  When
                        you  newly  register  a launcher for the extension with no
                        registration, you should select "NewEntry".  If you  input
                        a null line when you input a command for the launcher, the
                        existent launcher registration is deleted.
              Archiver  Change the archiver command registration for  each  exten-
                        sion.   When you newly register a archiver command for the
                        extension with no registration, you should select  "NewEn-
                        try".  If you input a null line both when you input a com-
                        mand for pack/unpack, the existent archiver command regis-
                        tration is deleted.
              DOS drive Change the floppy drive registration.  When you newly reg-
                        ister a floppy drive for the drive name with no  registra-
                        tion,  you  should select "NewEntry".  If you input a null
                        line when you input a device  name,  the  existent  floppy
                        drive registration is deleted.  (UNIX)
              Save      Save the configurations changed with the customizer into a
                        file, or cancel configurations to restore to the  previous
                                  ration for the same target is overwritten at the
                                  same  place  as  possible.   The  configurations
                                  which are not set up at present and the configu-
                                  rations  which  are  not  supported  by the cus-
                                  tomizer are remains as it is.
    
                        When you specify the range of categories,  all  categories
                        are  selected by default, then you should turn on/off each
                        selection with [Space] and decide with [Return].
    
           If you try to exit from the customizer without  saving  after  changing
           any configuration, you will be confirmed whether if it is right to exit
           without saving.  While the changed configurations themselves are  valid
           even  if you exit without saving, when you want them to be valid in the
           next invoked fd, you must save  them  into  the  initial  configuration
           file.
    
    
    

    ENVIRONMENT VARIABLES

           The following environment variables are valid in fd.  These environment
           variables can be valid if they are defined as the  internal  variables.
           You can specify them as the command line options in '-NAME=value' form.
           But the variables followed by * cannot be use with the  prefix  FD_  as
           the environment variables.
    
           ADJTTY        Reset  the  terminal  mode  forcedly to the normal state,
                         when fd is finished.  Invoking fd can adjust the terminal
                         rightly from the state displaying broken characters.  Any
                         value except 0 and null effects valid.  (UNIX)
    
           ANSICOLOR     Colorize the file display.  When the terminal  which  you
                         use  supports  the  color control escape sequence of ANSI
                         standard, each file is displayed with color according  to
                         its  file  type.  If the value is 1, it is colorized.  If
                         the value is 2, the background  color  is  forced  to  be
                         black, for the case that the foreground color is the same
                         as the background color and  indistinguishable.   If  the
                         value is 3, the foreground color is forced to be black.
    
           ANSIPALETTE   Specify  color  palette  according  to file type when the
                         file display is colorized.  This variable value  consists
                         of  a numeric value whose maximum columns are 11 columns.
                         The number of each column shows  a  color  number,  which
                         specifies  the  color of file type corresponding with its
                         column.  The following are correspondence of  the  column
                         number to the file type.
                             1    normal file
                             2    background
                             3    directory
                             4    unwritable file
                             5    unreadable file
                             6    symbolic link
                             7    socket (or system file on MS-DOS)
                             7    white
                             8    default color for foreground
                             9    default color for background
    
                         The color number 8 is forced to be black, if the value of
                         ANSICOLOR  the  variable  is  3.   The  color number 9 is
                         forced to be black, if the value of ANSICOLOR  the  vari-
                         able is 2.
    
                         When the columns are less than 11 or this variable is not
                         set, the standard color palette will be applied  for  the
                         file  type corresponding with the following columns.  The
                         standard color palette is described with the above  color
                         number as 89624351888.
    
           AUTOUPDATE    Specify  the  interval in seconds to update automatically
                         the browser screen or the  tree  screen.   When  the  key
                         input idles for the specified seconds, the current infor-
                         mation of file list will be updated.  If this value is 0,
                         the screen will never updated automatically.  The default
                         value is 0.
    
           BASICCUSTOM   Limit the internal variables for  configuration  only  to
                         basic variables in the customizer, to hide advanced vari-
                         ables.  Any value except 0 and null effects valid.
    
           CDPATH*       Specify the search  path  when  an  argument  of  cd  the
                         builtin  command  does not start with /.  You can specify
                         multiple paths separating with ':'.  No  search  path  is
                         specified by default.
    
           COLUMNS*      The  variable  for  the columns of a terminal screen.  If
                         some value is set, this value will be replaced  automati-
                         cally according to changing the screen size.  If no value
                         is set, this value will remain unset.
    
           COMSPEC       Specify the shell used to invoke a batch file.  If  unde-
                         fined,  the  shell defined by SHELL the internal variable
                         or \COMMAND.COM is used.  (DOS)
    
           COPYCMD*      Specify the default options used by copy the builtin com-
                         mand.
    
           DEFCOLUMNS    Specify  the  columns  displayed in the screen when fd is
                         invoked.  The default value is 2.   If  you  specify  the
                         value except 1, 2, 3 and 5, it is ignored.
    
           DEFKCODE      Specify  the  system  default  Kanji code.  The arguments
                         passed to external commands invoked from fd will be  con-
                         verted  into  the  specified  Kanji  code.   When you use
                         macros such as %C and %JJ, it will be converted into  the
                         Kanji  code  according  to each macro.  JIS8, JUNET, HEX,
                             UTF8-iconv     UTF-8 for iconv
                             default        no convert
    
           DIRCOUNTLIMIT Specify  the maximum number of files read from the direc-
                         tory in the tree screen.  When the directory  trailed  by
                         '>'  has  no  sub  directory,  the expanded result is not
                         changed.  If the number of files (including  directories)
                         in the directory is within this value, the directory with
                         no sub directory is  not  trailed  '>'  from  the  first.
                         Moreover, the file list in the directory displayed on the
                         right of screen is not displayed  over  this  value.   If
                         this  value is 0, you can realize a comfortable operation
                         speed even in the slow machine.  The default value is  50
                         files.
    
           DIRCMD*       Specify  the default options used by dir the builtin com-
                         mand.
    
           DIRHIST       Specify the maximum number  of  the  directory  histories
                         which  can  be referred by the directory input line.  The
                         default value is 50.  If this value is 0, you  can  refer
                         to no directory history.
    
           DIRHISTFILE   Specify  the name of the directory history file which can
                         be referred by the  directory  input  line.   Unless  you
                         specify  it,  the  directory  history  is  not loaded nor
                         saved.  The default value is not specified.
    
           DISPLAYMODE   Specify the filename display mode of the file  list  when
                         fd  is invoked.  Each of the symbolic link mode, the file
                         type symbol mode and the dot file  display  mode  can  be
                         selected individually.  The default value is 0.  The fol-
                         lowing are specifiable values.
                             0    standard
                             1    SYMLINK
                             2                FILETYPE
                             3    SYMLINK &   FILETYPE
                             4                             DOTFILE

           PS4*          Specify  the prompt string with which command strings are
                         displayed when you do set -x.
    
           PTYINKCODE    Specify the Kanji code  for  the  string  passed  to  the
                         pseudo terminal.  The string, which is converted from the
                         Kanji code specified by  INPUTKCODE  to  the  Kanji  code
                         specified  by  this command, is inputted to any processes
                         running on the pseudo terminal.  This  variable  has  the
                         individual  value  for  each pseudo terminal, so that you
                         should change value of the variable on the pseudo  termi-
                         nal to change the input Kanji code of the pseudo terminal
                         key as is, inputting the key name to be sent, terminating
                         forcedly  the  process  running  in  the pseudo terminal,
                         changing to the next window, invoking the Kana-Kanji IME.
                         In  "InputCode",  you  can  use the key name like as bind
                         command, and also the Kanji code number used in the Kana-
                         Kanji  IME  mode.   But you cannot select "NextWindow" in
                         the non-split window mode.   The  default  value  is  not
                         specified.  (UNIX)
    
           PTYMODE       Use  the pseudo terminal to invoke external commands.  In

                         for every windows will be opened and enable you to handle
                         simultaneously multiple external commands via  terminals.
                         If  the  terminal  in  use can not provide some functions
                         required for the terminal emulation, the pseudo  terminal
                         may  not  work  correctly.   Any  value except 0 and null
                         effects valid.  (UNIX)
    
           PTYOUTKCODE   Specify the Kanji code for the  string  passed  from  the
                         pseudo terminal.  The string, which is converted from the
                         Kanji code specified by this command to  the  Kanji  code
                         specified  by  LANGUAGE,  is displayed from any processes
                         running on the pseudo terminal.  This  variable  has  the
                         individual  value  for  each pseudo terminal, so that you
                         should change value of the variable on the pseudo  termi-

                         minal.  Some termcap(5) or terminfo(5)  may  cause  unex-
                         pected  behavior of the pseudo terminal, you should spec-
                         ify the effective terminal name in your environment.  The
                         default value is vt100.  (UNIX)
    
           PWD*          The  variable for the current directory with the absolute
                         representation.  If some value is set, this value will be
                         replaced  automatically according to changing the current
                         directory.  If no value is set, this  value  will  remain
                         unset.  If this is passed as an environment variable when
                         invoked, and this value and the current  directory  indi-
                         cate the same directory logically, then it is used as the
                         default value for the current directory.   It  is  useful
                         when  you  want to specify the logical pathname following
                         symbolic links.
    
                         tiple  mount  points separating with ':'.  You are enough
                         to specify only the top directory mounted by CD-ROM, then
                         the  pseudo  RockRidge Extension function is valid in all
                         of the directories under that directory.  This is no more
                         than  a  pseudo  extension, which only replaces filenames
                         according to TRANS.TBL, and  cannot  handle  some  CD-ROM
                         which  has  an inconsistent TRANS.TBL.  No mount point is
                         specified by default.
    
           SAVEDIRHIST   Specify the maximum number saved to the directory history
                         file.   The  default value is 50.  If this value is 0, no
                         directory history file is saved.
    
           SAVEHIST      Specify the maximum number saved to the  command  history
                         file.   The  default value is 50.  If this value is 0, no
                         command history file is saved.
    
           SECOND        Display the second in the clock of the title  line.   But
                         the  clock  is  adjusted  correctly every 10 seconds, and
                         some gap from the real time  will  be  occurred  in  this
                         span.  Any value except 0 and null effects valid.
    
           SHELL         When  the filename part of this specified value is rfd or
                         rfdsh, the shell becomes a restricted shell as well as -r
                         option  when  invoked.   This  variable  also specify the
                         shell which can be invoked from EXECUTE_SH.
    
           SIZEINFO      Display the file size information  line  at  the  top  of
                         screen.   The total size displayed here is not the sum of
                         bytes but the sum of disk block size  occupied  actually.
                         Any value except 0 and null effects valid.
    
           SORTTREE      Sort  directories  in  the  tree screen.  The sorted type
                         specified by SORT_DIR is used, but they can not be sorted
                         when  it  is  "by size" or "by timestamp".  The directory
                         included in the current directory path is  always  placed
                         on  the  top  of  directory  tree,  with no regard to the
                         sorted type.  Any value except 0 and null effects  valid.
    
           SORTTYPE      The  file  list  in  the  browser screen is not sorted by
                         default, but placed in order registered in the directory.
                         This  variable  specify  it to be sorted by default.  The
                         following are specifiable values.
                             0    not sort

                             100-113   keep the last sorted type
                             200-213   keep it also in archive browser
    
                         able one as this value after  invoked  for  some  strange
                         terminal display and key input.
    
           THRUARGS      Pass  through  the pathnames as is, which is specified as
                         the startup arguments.  Fd  expands  the  meta  character
                         such  as  ~  and  ${#}  in  the given pathname by itself,
                         because the obsolete low-level shell cannot support these
                         expansion extended by POSIX.  Fd can sometimes expand the
                         pathname given by the shell into the unexpected string as
                         a result of duplicate expansion, because the latest high-
                         level shell  generally  support  these  expansion.   This
                         variable  will  be  suppress  the expansion of arguments.
                         Any value except 0 and null effects valid.
    
           TMPDIR        Specify the working directory where the archiver  command
                         temporarily  unpack  files  in  the  archive  file.   The
                         default value is /tmp.
    
                         (On MS-DOS version, The default value is '.'.)
    
           TMPUMASK      Specify the file creation mask with octal expression  for
                         files and directories created temporarily in TMPDIR.  But
                         the mask value set by umask the builtin command is prior,
                         then  actual  mask  value is the logical OR of this value
                         and umask value.
    
           TRADLAYOUT    Use the traditional screen layout based on  the  original
                         "FD".   In this layout, the file size information will be
                         always displayed, whether SIZEINFO is set or  not.   When
                         the screen width is less than 80 columns, this specifica-
                         tion is invalid.  Any value except  0  and  null  effects
                         valid.
    
           UNICODEBUFFER Hold the UNICODE translation table on memory.  It will be

                         UTF-8.   You  should  set this if you have enough memory.
                         Any value except 0 and null effects valid.
    
           URLDRIVE      Validate the function of the URL drive.  Any value except

           URLTIMEOUT    Specify the timeout in seconds, when the URL drive commu-
                         nicates  with  the  host.   If the communication from the
                         host is lost for the time specified, the communication is
                         regarded  as  invalid and its connection will be shutdown
                         forcedly.  If this value is 0 second, the timeout  opera-
                         tion  is  invalid  to  continue waiting response forever.
                         The default value is 0 second.  (UNIX)
    
           USEGETCURSOR  Use the VT100 compatible escape sequence getting the cur-
                         sor position in order to get the terminal size.  When the
                         screen size of fd doesn't correspond  with  the  terminal
                         size, this variable can be sometimes valid.  On some ter-
                         minals which don't support the  escape  sequence  getting
                         the  cursor  position,  the operation may be stopped.  In
                         this case, it is continued by inputting 'R' from the key-
                         board.   Any  value  except  0  and  null  effects valid.

           NOCONVPATH    Specify the Kanji code for filename per directory,  which
                         is  prior  to FNAMEKCODE.  You can specify multiple path-
                         names separating with ':'.  You  are  enough  to  specify
                         only  the  top  directory where you want to use the Kanji
                         code, then you can use the  Kanji  code  in  all  of  the
                         directories under that directory.  In the directory which
                         is described in NOCONVPATH, no Kanji  code  is  converted
                         ignoring  the value of FNAMEKCODE.  No pathname is speci-
                         fied by default.  (UNIX)
    
    
    

    MULTI LANGUAGE SUPPORT

           Fd processes the Kanji character-set to  input/output  as  "EUC-JP"  or
           "Shift  JIS" according to setting in compile.  The the pathname includ-
           ing Kanji is displayed in consideration for the 2nd byte  character  in
           Kanji.  You can dynamically select Kanji code to input/output with LAN-
           GUAGE, INPUTKCODE and FNAMEKCODE the internal variable.  You can  input
           Japanese string with the Kana-Kanji IME mode.
    
           You can use Kanji in the command macro and the command string, but can-
           not use Kanji as the value of the internal variables.  You  cannot  use
           the  multibyte  symbol character as the meta character, such as '%' and
           '"' and so on, Kanji character is not counted as  1  character  in  the
           wildcard search.
    
           And  when  you give the non-standard Kanji code for the OS to the shell
           with the parameter macro such as %JJ, some Kanji is converted into  the
           code  including  the  meta  character such as '$' and '\' and so on, to
           cause unexpected behavior.  In that case, you can probably avoid it  by
           quoting the string to be converted with %'.
    
    
    

    AUTHOR

           Takashi SHIRAI <shirai@unixusers.net>
           The  original  "FD"  for  MS-DOS  was  created  and  released by A.Idei
           <SDI00544@niftyserve.or.jp> for the first time, in 1989.  Fd  was  cre-
           ated for UNIX from scratch following that implementation, in 1995.
    
    
    

    FILES

                     The UNICODE translation table, which is installed in the same
                     directory as the executable binary of fd
           fd-dict.tbl
                     The  Kana-Kanji  translation  dictionary   file,   which   is
                     installed  in  the same directory as the executable binary of
                     fd
    
           fd2rc     The systemwide initial configuration file for  fd  on  MS-DOS
                     version,  which must be prepared in the same directory as the
                     executable binary of fd
           $HOME\fd2.rc
                     The individual initial configuration file for  fd  on  MS-DOS
                     version
           $HOME\fdsh.rc
                     The  individual initial configuration file for fdsh on MS-DOS
                     version
           $HOME\fd.hst
                     The command history file on MS-DOS version by default
    
    
    

    LIMITATIONS

           Some terminals cannot send the input of certain function keys and  spe-
           cial  keys.   The  sequence  compatible  with  VT200 is assigned as the
           default sequence which is not registered in termcap(5),  and  when  the
           terminal cannot support this, the key receipt or the screen control due
           to be brought by this is not available.

    BUGS

           When files in an archive file are  packed  with  a  pathname  including
           "..",  the archive browser cannot work normally.  The symbolic links in
           an archive file cannot be unpacked individually.
    
           The user interface is cheap.
