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 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.
- 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 capability), 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 terminal 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 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 elasped time.
- -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.
