nroff(1)						      General Commands Manual							  nroff(1)

NAME
nroff - Formats text SYNOPSIS
nroff [option...] [file...] OPTIONS
Options can appear in any order as long as they precede any file names. Prints only pages whose page numbers appear in the comma-separated list of numbers and ranges specified in the list argument. A range of N-M means pages N through M. An argument of the form -N means from the beginning of the text up to page N. An argument of the form N- means from page N to the end of the text. Directs nroff to use N as the number for the first generated page. Stops every N pages. The nroff command halts after formatting N pages to allow paper reloading or changing and resumes when it receives a new line signal. The default for N is 1. Prepends the macro file /usr/share/lib/tmac/tmac.name to the files specified in the nroff command line. Sets register a to N. The register specification is limited to a single character. Reads from standard input after the specified list of files is exhausted. Invokes the simultaneous input-output mode of the .rd request. Prepares output for the specified terminal. The name argument refers to tabname files in /usr/share/lib/term. The default name is lpr, which refers to a dumb 10-pitch printer with no halfline or upline capability. Produces equally-spaced words in adjusted lines, using full terminal resolution. Uses output tabs during horizontal spacing to speed output and reduce output character count. Tab settings are assumed to be every eight nominal character widths. DESCRIPTION
The nroff command formats text in the specified files for typewriter-like devices. If no file argument is present, nroff reads from stan- dard input. An argument consisting of a single minus sign (-) is taken to be a file name corresponding to standard input. FILES
Temporary file Standard macro files Terminal driver tables for nroff SEE ALSO
Commands: checknr(1), man(1), neqn(1), soelim(1), tbl(1), catman(8) Files: term(4), man(5), me(5), ms(5), rsml(5) nroff(1)
