troff, nroff - text formatting and typesetting

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

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

Troff formats text in the named files for printing on a typesetter. Nroff does the same, but produces output suitable for typewriter-like devices.

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 are:

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.
Number first generated page N.
Process the macro file /usr/share/9base/troff/tmac/tmac.name before the input files.
Set register a (one character name) to N.
Read standard input after the input files are exhausted.
Invoke the simultaneous input-output mode of the rd request.
Produce output suitable for typewriter-like devices.

Send a printable textual approximation of the results to the standard output.
Prepare output for typesetter dest:
(The default.) PostScript printers with preprocessing to handle Unicode characters encoded in UTF
Regular PostScript printers
Mergenthaler Linotron 202
Take font information from directory dir.

Halt prior to every N pages (default N=1) to allow paper loading or changing.
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).
Produce equally-spaced words in adjusted lines, using full terminal resolution.
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.
