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 phototype-
setter; 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 cas-
settes, and resume when the typesetter's start button is pressed.
-mname Prepend the macro file /usr/share/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.
-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
-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.
The directory fontdir contains the font width tables instead of the default direc-
tory /usr/share/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.
