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 Graphic Systems C/A/T phototypesetter; nroff is used for for typewriter-like devices. Their capabilities are described in the Nroff/Troff user's manual. 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 corre- sponding to the standard input. The options, which may appear in any order so long as they appear before the files, are: -olist Print only pages whose page numbers appear in the comma-separated list of numbers and ranges. A range N-M means pages N through M; an initial -N means from the beginning to page N; and a final N- means from N to the end. -nN Number first generated page N. -sN Stop every N pages. Nroff will halt prior to every N pages (default N=1) to allow paper loading or changing, and will resume upon receipt of a newline. Troff will stop the phototypesetter every N pages, produce a trailer to allow changing cassettes, and resume when the typesetter's start button is pressed. -mname Prepend the macro file /usr/share/tmac/ to the input files. -raN Set register a (one-character) to N. -i Read standard input after the input files are exhausted. -q Invoke the simultaneous input-output mode of the rd request. Troff only -t Direct output to the standard output instead of the phototypesetter. -f Refrain from feeding out paper and stopping phototypesetter at the end of the run. -w Wait until phototypesetter is available, if currently busy. -b Report whether the phototypesetter is busy or available. No text processing is done. -a Send a printable ASCII approximation of the results to the standard output. -pN Print all characters in point size N while retaining all prescribed spacings and motions, to reduce phototypesetter elapsed time. -Ffontdir The directory fontdir contains the font width tables instead of the default directory /usr/share/fonts. This option can be used to produce output for devices besides the phototypesetter. If the file /usr/adm/tracct is writable, troff keeps phototypesetter accounting records there. The integrity of that file may be secured by making troff a 'set user-id' program. FILES

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/ 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
