NAME
       troff, nroff - text formatting and typesetting

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

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

DESCRIPTION
       Troff formats text in the named files for printing on a Graphic Systems
       C/A/T phototypesetter; nroff is used for for  typewriter-like  devices.
       Their capabilities are described in the Nroff/Troff users 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
              (default N=1) to allow  paper  loading  or  changing,  and  will
              resume  upon  receipt  of a newline.  Troff will stop the photo‐
              typesetter 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/tmac.name  to  the  input
              files.

       -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.

       <i>TT<i>rr<i>oo<i>ff<i>ff <i>oo<i>nn<i>ll<i>yy

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

       -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  elapsed
              time.

       -Ffontdir
              The  directory fontdir contains the font width tables instead of
              the default directory /usr/lib/fonts. This option can be used to
              produce output for devices besides the phototypesetter.

       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.

FILES
       /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
