TROFF(1)

NAME
troff, nroff - text formatting and typesetting

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

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

DESCRIPTION
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:

-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 loading 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 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.
