    tput

    
    
    

    SYNOPSIS

           tput [-Ttype] capname [parms ... ]
           tput [-Ttype] init
           tput [-Ttype] reset
           tput [-Ttype] longname
           tput -S  <<
           tput -V
    
    
    

    DESCRIPTION

           The  tput utility uses the terminfo database to make the values of ter-
           minal-dependent capabilities and information  available  to  the  shell
           (see  sh(1)),  to  initialize or reset the terminal, or return the long
           name of the requested terminal type.  The result depends upon the capa-
           bility's type:
    
                  string
                       tput writes the string to the standard output.  No trailing
                       newline is supplied.
    
                  integer
                       tput writes the decimal value to the standard output,  with
                       a trailing newline.
    
                  boolean
                       tput  simply sets the exit code (0 for TRUE if the terminal
                       has the capability, 1 for FALSE if it does not), and writes
                       nothing to the standard output.
    
           Before  using  a value returned on the standard output, the application
           should test the exit code (e.g., $?, see sh(1)) to be  sure  it  is  0.
           (See  the EXIT CODES and DIAGNOSTICS sections.)  For a complete list of
           capabilities and the capname associated with each, see terminfo(5).
    
           -Ttype indicates the type of terminal.  Normally this option is  unnec-
                  essary,  because the default is taken from the environment vari-
                  able TERM.  If -T is specified, then the shell  variables  LINES
                  and COLUMNS will be ignored,and the operating system will not be
                  queried for the actual screen size.
    
           capname
                  indicates the capability from the terminfo database.  When term-
                  cap  support is compiled in, the termcap name for the capability
                  is also accepted.
    
           parms  If the capability is a string that takes parameters,  the  argu-
                  ments parms will be instantiated into the string.
    
                  Most  parameters  are numbers.  Only a few terminfo capabilities
                  require string parameters; tput uses a table to decide which  to
                  pass  as  strings.  Normally tput uses tparm (3X) to perform the
                  substitution.  If no parameters are given  for  the  capability,
                  tput writes the string without performing the substitution.
    
           init   If  the terminfo database is present and an entry for the user's
                  terminal exists (see -Ttype, above), the following will occur:
    
                  (1)    if present, the terminal's initialization strings will be
                         output as detailed in the terminfo(5) section on Tabs and
                         Initialization,
    
                  (2)    any delays (e.g., newline) specified in the entry will be
                         set in the tty driver,
    
                  (3)    tabs  expansion will be turned on or off according to the
                         specification in the entry, and
    
                  (4)    if tabs are not  expanded,  standard  tabs  will  be  set
                         (every 8 spaces).
    
                  If  an  entry does not contain the information needed for any of
                  the four  above  activities,  that  activity  will  silently  be
                  skipped.
    
           reset  Instead  of  putting  out initialization strings, the terminal's
                  reset strings will be output if present (rs1, rs2, rs3, rf).  If
                  the  reset  strings  are not present, but initialization strings
                  are, the initialization  strings  will  be  output.   Otherwise,
                  reset acts identically to init.
    
           longname
                  If  the terminfo database is present and an entry for the user's
                  terminal exists (see -Ttype above), then the long  name  of  the
                  terminal will be put out.  The long name is the last name in the
                  first  line  of  the  terminal's  description  in  the  terminfo
                  database [see term(5)].
    
           If  tput  is invoked by a link named reset, this has the same effect as
           tput reset.  See tset for comparison, which has similar behavior.
    
    
    

    EXAMPLES

           tput init
                Initialize the terminal according to the type of terminal  in  the
                environmental  variable  TERM.  This command should be included in
                everyone's .profile after the environmental variable TERM has been
                exported, as illustrated on the profile(5) manual page.
    
           tput -T5620 reset
                Reset  an  AT&T  5620 terminal, overriding the type of terminal in
                the environmental variable TERM.
    
           tput cup 0 0
                Send the sequence to move the cursor to row 0, column 0 (the upper
                left  corner  of  the  screen,  usually known as the "home" cursor
                position).
                in your name: ${offbold}\c"
    
           tput hc
                Set  exit  code to indicate if the current terminal is a hard copy
                terminal.
    
           tput cup 23 4
                Send the sequence to move the cursor to row 23, column 4.
    
           tput cup
                Send the terminfo string for cursor-movement, with  no  parameters
                substituted.
    
           tput longname
                Print  the  long  name  from the terminfo database for the type of
                terminal specified in the environmental variable TERM.
    
                tput -S <<!
                > clear
                > cup 10 10
                > bold
                > !
    
                This example shows tput processing  several  capabilities  in  one
                invocation.   It  clears  the screen, moves the cursor to position
                10, 10 and turns on bold (extra bright) mode.  The list is  termi-
                nated by an exclamation mark (!) on a line by itself.

                  tabs);  for  more information, see the "Tabs and Initialization"
                  section of terminfo(5)
    
    
    

    EXIT CODES

           If the -S option is used, tput checks for errors from each line, and if
           any  errors  are  found, will set the exit code to 4 plus the number of
           lines with errors.  If no errors are found, the exit  code  is  0.   No
           indication  of which line failed can be given so exit code 1 will never
           appear.  Exit codes 2, 3, and 4 retain their usual interpretation.   If
           the  -S  option  is not used, the exit code depends on the type of cap-
           name:
    
                boolean
                       a value of 0 is set for TRUE and 1 for FALSE.
    
                string a value of 0 is set if the capname is defined for this ter-
                       minal  type  (the  value of capname is returned on standard

           exit codes.

                       the  terminfo(5)  database  for this terminal type, e.g.
                       tput -T450 lines and @TPUT@ -T2621 xmc)

    PORTABILITY

           The longname and -S options, and  the  parameter-substitution  features
           used in the cup example, are not supported in BSD curses or in AT&T/USL
           curses before SVr4.
    
           X/Open documents only the operands for clear, init and reset.  In  this
           implementation,  clear is part of the capname support.  Other implemen-
           tations of tput on SVr4-based systems such as Solaris, IRIX64 and  HPUX
           as  well  as  others  such as AIX and Tru64 provide support for capname
           operands.  A few platforms such as FreeBSD and NetBSD recognize termcap
           names  rather  than  terminfo capability names in their respective tput
           commands.
