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 argument consisting of a single minus (–) is taken to be a file name corresponding 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. –mnameProcess 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 loading or changing. –TnamePrepare 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 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.
