       troff, nroff - text formatting and typesetting

       troff [ option ] ...  [ file ] ...

       nroff [ option ] ...  [ file ] ...

       Troff formats text in the named files for printing on a Graphic Systems
       C/A/T phototypesetter; nroff for typewriter-like devices.  Their  capa‐
       bilities are described in the Nroff/Troff user's manual.

       If  no  file argument is present, the standard input is read.  An argu‐
       ment consisting of a single minus (-) is taken to be a file name corre‐
       sponding  to  the standard input.  The options, which may appear in any
       order so long as they appear before the files, are:

       -olist Print only pages whose page numbers appear  in  the  comma-sepa‐
              rated  list  of  numbers  and ranges.  A range N-M means pages N
              through M; an initial -N means from the beginning to page N; and
              a final N- means from N to the end.

       -nN    Number first generated page N.

       -sN    Stop every N pages.  Nroff will halt prior to every N pages (de‐
              fault N=1) to allow paper loading or changing, and  will  resume
              upon  receipt of a newline.  Troff will stop the phototypesetter
              every N pages, produce a trailer to  allow  changing  cassettes,
              and resume when the typesetter's start button is pressed.

       -mname Prepend  the  macro  file  /usr/lib/tmac/  to the input

       -raN   Set register a (one-character) to N.

       -i     Read standard input after the input files are exhausted.

       -q     Invoke the simultaneous input-output mode of the rd request.

       Nroff only

       -Tname Prepare output for specified terminal.  Known names are  37  for
              the  (default) Teletype Corporation Model 37 terminal, tn300 for
              the GE TermiNet 300 (or any terminal without half-line  capabil‐
              ity),  300S for the DASI-300S, 300 for the DASI-300, and 450 for
              the DASI-450 (Diablo Hyterm).

       -e     Produce equally-spaced words in adjusted lines, using full  ter‐
              minal resolution.

       -h     Use  output  tabs  during horizontal spacing to speed output and
              reduce output character count.  Tab settings are assumed  to  be
              every 8 nominal character widths.

       Troff only

       -t     Direct  output  to the standard output instead of the phototype‐

       -f     Refrain from feeding out paper and stopping  phototypesetter  at
              the end of the run.

       -w     Wait until phototypesetter is available, if currently busy.

       -b     Report  whether  the  phototypesetter  is busy or available.  No
              text processing is done.

       -a     Send a printable ASCII approximation of the results to the stan‐
              dard output.

       -pN    Print  all  characters  in point size N while retaining all pre‐
              scribed spacings and motions, to reduce phototypesetter  elasped

       -g     Prepare  output  for a GCOS phototypesetter and direct it to the
              standard output (see gcat(1)).

       If the file /usr/adm/tracct is writable,  troff  keeps  phototypesetter
       accounting records there.  The integrity of that file may be secured by
       making troff a `set user-id' program.

       /usr/lib/suftab       suffix hyphenation tables
       /tmp/ta*              temporary file
       /usr/lib/tmac/tmac.*  standard macro files
       /usr/lib/term/*       terminal driving tables for nroff
       /usr/lib/font/*       font width tables for troff
       /dev/cat              phototypesetter
       /usr/adm/tracct       accounting statistics for /dev/cat
