           It is possible to have whitespace between a command line option and its


           This manual page describes the GNU version of troff.  It is part of the
           groff  document  formatting system.  It is functionally compatible with
           UNIX troff, but has many extensions,  see  groff_diff(7).   Usually  it
           should  be  invoked using the groff(1) command which will also run pre-
           processors and postprocessors in the appropriate  order  and  with  the
           appropriate options.


           -a        Generate an ASCII approximation of the typeset output.
           -b        Print  a  backtrace with each warning or error message.  This
                     backtrace should help track down the cause of the error.  The
                     line  numbers  given  in the backtrace may not always be cor-
                     rect, for troff's idea of line numbers gets confused by as or
                     am requests.
           -c        Disable color output (always disabled in compatibility mode).
           -C        Enable compatibility mode.
           -dname=s  Define c or name to be a string s; c must  be  a  one  letter
           -E        Inhibit  all error messages of troff.  Note that this doesn't
                     affect messages output to standard error  by  macro  packages
                     using the tm or tm1 requests.
           -ffam     Use fam as the default font family.
           -Fdir     Search  in  directory (or directory path) dir for subdirecto-
                     ries devname (name is the name of the device) and  there  for
                     the  DESC  file  and  font  files.  dir is scanned before all
                     other font directories.
           -i        Read the standard input after all the named input files  have
                     been processed.
           -mname    Read in the file name.tmac.  If it isn't found, try
                     instead.  It will be first searched for in directories  given
                     with the -M command line option, then in directories given in
                     the GROFF_TMAC_PATH environment variable, then in the current
                     directory  (only  if  in  unsafe  mode),  the home directory,
           -rname=n  Set number register c or name to n; c must be a one character
                     name; n can be any troff numeric expression.
           -R        Don't load troffrc and troffrc-end.
           -Tname    Prepare output for device name, rather than the default ps.
           -U        Unsafe  mode.  This will enable the following requests: open,
                     opena, pso, sy, and pi.  For security reasons,  these  poten-
                     tially  dangerous  requests  are disabled otherwise.  It will
                     also add the current directory to the macro search path.
           -v        Print the version number.
           -wname    Enable warning name.  Available warnings are described in the
                     section WARNINGS below.  For example, to enable all warnings,
                     use -w all.  Multiple -w options are allowed.
           -Wname    Inhibit warning name.  Multiple -W options are allowed.
           -z        Suppress formatted output.


           The warnings that can be given by troff are divided into the  following
           categories.   The  name  associated with each warning is used by the -w
           and -W options; the number is used by the  warn  request,  and  by  the
           .warn register; it is always a power of 2 to allow bitwise composition.
                     |Bit   Code   Warning | Bit    Code      Warning   |
                     |  0      1   char    |  10     1024   reg         |

           break           4   In fill mode, lines which could not  be  broken  so
                               that  their  length  was less than the line length.
                               This is enabled by default.
           char            1   Non-existent  characters.   This  is   enabled   by
           ig         262144   Invalid   escapes  in  text  ignored  with  the  ig
                               request.  These are conditions that are errors when
                               they do not occur in ignored text.
           input       16384   Invalid input characters.
           mac           512   Use  of  undefined  strings, macros and diversions.
                               When an undefined string,  macro  or  diversion  is
                               used,  that  string  is  automatically  defined  as
                               empty.  So, in most cases, at most one warning will
                               be given for each name.
           missing      8192   Requests that are missing non-optional arguments.
           number          2   Invalid  numeric  expressions.   This is enabled by
           range          64   Out of range arguments.
           reg          1024   Use of undefined number registers.  When  an  unde-
                               fined  number  register  is  used, that register is
                               automatically defined to have a value of 0.  So, in
                               most  cases,  at most one warning will be given for
                               use of a particular name.
           right-brace  4096   Use of \} where a number was expected.
           scale          32   Meaningless scaling indicators.
           space       65536   Missing space between a request or  macro  and  its
                               argument.  This warning will be given when an unde-
                               fined name longer than two  characters  is  encoun-
                               tered,  and  the  first  two characters of the name
                               make a defined name.  The request or macro will not
                               be  invoked.   When this warning is given, no macro
                               is  automatically  defined.   This  is  enabled  by
                               default.  This warning will never occur in compati-
                               bility mode.
           syntax        128   Dubious syntax in numeric expressions.
           tab          2048   Inappropriate use of a tab character.   Either  use
                               of  a tab character where a number was expected, or
                               use of tab character in an unquoted macro argument.
           There are also names that can be used to refer to groups of warnings:
           all    All  warnings except di, mac, and reg.  It is intended that this
                  covers all warnings that are useful with traditional macro pack-
                  A colon separated list of directories in which to search for the
                  devname  directory.  troff will scan directories given in the -F
                  option   before   these,    and    in    standard    directories
                  (/usr/share/groff/site-font,     /usr/share/groff/,
                  /usr/lib/font) after these.


                  Initialization file (called before any other macro package).
                  Initialization file (called after any other macro package).
                  Macro files
                  Device description file for device name.
                  Font file for font F of device name.
           Note that troffrc and troffrc-end are neither searched in  the  current
           nor  in the home directory by default for security reasons (even if the
           -U  option  is  given).   Use  the  -M  command  line  option  or   the
           GROFF_TMAC_PATH  environment  variable  to add these directories to the
           search path if necessary.
