SYNOPSIS
groff [ -abeghilpstvzCEGNRSUVXZ ] [ -wname ] [ -Wname ] [ -mname ] [ -Fdir ] [ -Idir ] [ -Tdev ] [ -ffam ] [ -Mdir ] [ -dcs ] [ -rcn ] [ -nnum ] [ -olist ] [ -Parg ] [ -Larg ] [ files... ] It is possible to have whitespace between a command line option and its parameter.
DESCRIPTION
groff is a front-end to the groff document formatting sys- tem. Normally it runs the troff program and a postproces- sor appropriate for the selected device. Available devices are: ps For PostScript printers and previewers dvi For TeX dvi format. X75 For a 75 dpi X11 previewer. X100 For a 100dpi X11 previewer. ascii For typewriter-like devices. latin1 For typewriter-like devices using the ISO Latin-1 (ISO 8859-1) character set. utf8 For typewriter-like devices using the Unicode (ISO 10646) character set with UTF-8 encoding. cp1047 For typewriter-like devices which use the EBCDIC code page IBM cp1047 (e.g. OS/390 Unix). lj4 For an HP LaserJet4-compatible (or other PCL5-com- patible) printer. lbp For Canon CAPSL printers (LBP-4 and LBP-8 series laser printers). html To produce HTML output. The postprocessor to be used for a device is specified by the postpro command in the device description file. This can be overridden with the -X option. The default device is ps. It can optionally preprocess with any of pic, eqn, grn, grap, tbl, refer, or soelim. Options without an argument can be grouped behind a single -. A filename of - denotes the standard input. Groff Version 1.16.1 April 8, 2001 1 GROFF(1) GROFF(1) The grog command can be used to guess the correct groff command to use to format a file.
OPTIONS
-h Print a help message. -e Preprocess with eqn. -t Preprocess with tbl. -g Preprocess with grn. -G Preprocess with grap. -p Preprocess with pic. -s Preprocess with soelim. -Idir This option is as described in soelim(1). This option implies the -s option. -R Preprocess with refer. No mechanism is provided for passing arguments to refer because most refer options have equivalent commands which can be included in the file. See refer(1) for more details. -v Make programs run by groff print out their version number. -V Print the pipeline on stdout instead of executing it. -z Suppress output from troff. Only error messages will be printed. -Z Do not postprocess the output of troff. Normally groff will automatically run the appropriate post- processor. -Parg Pass arg to the postprocessor. Each argument should be passed with a separate -P option. Note that groff does not prepend - to arg before passing it to the postprocessor. -l Send the output to a printer. The command used for this is specified by the print command in the device description file. -Larg Pass arg to the spooler. Each argument should be passed with a separate -L option. Note that groff does not prepend - to arg before passing it to the postprocessor. Groff Version 1.16.1 April 8, 2001 2 GROFF(1) GROFF(1) -Tdev Prepare output for device dev. The default device is ps. -X Preview with gxditview instead of using the usual postprocessor. Groff passes gxditview a -printCom- mand option which will make the Print action do what groff would have done if the -l option had been given. This is unlikely to produce good results except with -Tps. -N Don't allow newlines with eqn delimiters. This is the same as the -N option in eqn. -S Safer mode. Pass the -S option to pic and use the -msafer macros with troff (enabled by default). -U Unsafe mode. Reverts to the old unsafe behaviour. -a -b -i -C -E -wname -Wname -mname -olist -dcs -rcn -Fdir -Mdir -ffam -nnum These are as described in troff(1).
ENVIRONMENT
GROFF_COMMAND_PREFIX If this is set X, then groff will run Xtroff instead of troff. This also applies to tbl, pic, eqn, grn, refer, and soelim. It does not apply to grap, grops, grodvi, grotty, grolj4, grohtml, and gxditview. GROFF_TMAC_PATH A colon separated list of directories in which to search for macro files. GROFF_TYPESETTER Default device. GROFF_FONT_PATH A colon separated list of directories in which to search for the devname directory. PATH The search path for commands executed by groff. Groff Version 1.16.1 April 8, 2001 3 GROFF(1) GROFF(1) GROFF_TMPDIR The directory in which temporary files will be cre- ated. If this is not set and TMPDIR is set, tempo- rary files will be created in that directory. Oth- erwise temporary files will be created in /tmp. The grops(1) and refer(1) commands can create tem- porary files.
FILES
/usr/share/groff_font/devname/DESC Device description file for device name. /usr/share/groff_font/devname/F Font file for font F of device name. Note that on EBCDIC hosts, output devices ascii, latin1, and utf8 aren't available. Similarly, cp1047 is not available on ASCII based operating systems.
EXAMPLE
To print the man page foo.1 to the standard output using the latin-1 output device and less as the pager, the fol- lowing command can be used: groff -mandoc -Tlatin1 foo.1 | less Alternatively, you can say groff -m mandoc -Tlatin1 foo.1 | less
