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 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/tmac.name 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

NAME
troff - typeset or format documents SYNOPSIS
troff [-a] [-f] [-Fdir] [-i] [-mname] [-nN] [-olist] [-raN] [-sN] [-Tdest] [-uN] [-z] [filename]... DESCRIPTION
troff formats text in the filenames for typesetting or laser printing. Input to troff is expected to consist of text interspersed with for- matting requests and macros. If no filename argument is present, troff reads standard input. A minus sign (-) as a filename indicates that standard input should be read at that point in the list of input files. The output of troff is usually piped through dpost(1) to create a printable postscript file (see EXAMPLES). OPTIONS
The following options are supported. They may appear in any order, but all must appear before the first filename. -a Send an ASCII approximation of formatted output to standard output. (Note: a rough ASCII version can also be printed out on ordinary terminals with an old and rarely used command, /usr/bin/ta.) -f Do not print a trailer after the final page of output or cause the postprocessor to relinquish control of the device. -Fdir Search directory dir for font width or terminal tables instead of the system default directory. -i Read standard input after all input files are exhausted. -mname Prepend the macro file /usr/share/lib/tmac/name to the input filenames. Note: most references to macro packages include the leading m as part of the name; for example, the man(5) macros reside in /usr/share/lib/tmac/an. The macro directory can be changed by setting the TROFFMACS environment variable to a specific path. Be certain to include the trailing '/' (slash) at the end of the path. -nN Number the first generated page N. -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. -q Quiet mode in nroff; ignored in troff. -raN Set register a (one-character names only) to N. -sN Stop the phototypesetter every N pages. On some devices, troff produces a trailer so you can change cassettes; resume by press- ing the typesetter's start button. -Tdest Prepare output for typesetter dest. The following values can be supplied for dest: post A PostScript printer; this is the default value. The output of the -T option must go through dpost(1) before it is sent to a PostScript printer to obtain the proper output. aps Autologic APS-5. -uN Set the emboldening factor for the font mounted in position 3 to N. If N is missing, then set the emboldening factor to 0. -z Suppress formatted output. Only diagnostic messages and messages output using the .tm request are output. OPERANDS
The following operand is supported: filename The file containing text to be processed by troff. EXAMPLES
Example 1 Using troff The following example shows how to print an input text file mytext, coded with formatting requests and macros. The input file contains equations and tables and must go through the tbl(1) and eqn(1) preprocessors before it is formatted by troff with ms macros, processed by dpost(1), and printed by lp(1): tbl mytext | eqn | troff -ms | dpost | lp FILES
/tmp/trtmp temporary file /usr/share/lib/tmac/* standard macro files /usr/lib/font/* font width tables for alternate mounted troff fonts /usr/share/lib/nterm/* terminal driving tables for nroff ATTRIBUTES

troff is not 8-bit clean because it is by design based on 7-bit ASCII. Previous documentation incorrectly described the numeric register yr as being the "Last two digits of current year". yr is in actuality the number of years since 1900. To correctly obtain the last two digits of the current year through the year 2099, the definition given below of string register yy may be included in a document and subsequently used to display a two-digit year. Note that any other available one- or two-character register name may be substituted for yy. ." definition of new string register yy--last two digits of year ." use yr (# of years since 1900) if it is < 100 .ie (yr<100 .ds yy (yr .el { ." else, subtract 100 from yr, store in ny .nr ny (yr-100 .ie (ny>9 { ." use ny if it is two digits .ds yy (ny ." remove temporary number register ny .rr ny } .el {.ds yy 0 ." if ny is one digit, append it to 0 .as yy (ny .rr ny } } SunOS 5.11 22 Jul 1998 troff(1)
