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 user's manual.

If no file argument is present, the standard input is read. An argument consisting of a single minus (-) is taken to be a file name corresponding 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-separated 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 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/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.
Troff only
-t: Direct output to the standard output instead of the phototypesetter.
-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 standard output.
-pN: Print all characters in point size N while retaining all prescribed 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.
