NAME
troff, nroff, dpost - text formatting and typesetting
SYNOPSIS
troff [ option ... ] [ file ... ]
dpost [ -f ] [ file ... ]
nroff [ option ... ] [ file ... ]
DESCRIPTION
Troff formats text in the named files for printing on a typesetter,
emitting a textual intermediate format called `typesetter-independent
troff output', understood by programs such as proof(1) and lp(1), but
also by a troff post-processor named dpost, which emits corresponding
Postscript. Under -f, dpost also emits Postscript font definitions as
needed. Nroff does the same as troff, but produces output suitable for
typewriter-like devices, usually without further post-processing, but
see col(1).
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 are:
-olist Print pages in the comma-separated list of numbers and ranges.
A range N-M means N through M; initial -M means up to M; final
N- means from N to the end.
-nN Number first generated page N.
-mname Process the macro file /sys/lib/tmac/tmac.name before the input
files.
-raN Set register a (one character name) to N.
-i Read standard input after the input files are exhausted.
-q Invoke the simultaneous input-output mode of the rd request.
-N Produce output suitable for typewriter-like devices.
Typesetter devices (not -N) only
-a Send a printable textual approximation of the results to the
standard output.
-Tdest Prepare output for typesetter dest:
-Tutf (The default.) PostScript printers with preprocessing
to handle Unicode characters encoded in UTF
-Tpost Regular PostScript printers
-T202 Mergenthaler Linotron 202
-Fdir Take font information from directory dir.
Typewriter (-N) output only
-sN Halt prior to every N pages (default N=1) to allow paper load‐
ing or changing.
-Tname Prepare output for specified terminal. Known names include utf
for the normal Plan 9 UTF encoding of the Unicode Standard
character set (default), 37 for the Teletype model 37, lp
(`line-printer') for any terminal without half-line capability,
450 for the DASI-450 (Diablo Hyterm), and think (HP ThinkJet).
-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.
