It is possible to have whitespace between a command line option and its
parameter.
groff is a front-end to the groff document formatting system. Normally
it runs the troff program and a postprocessor appropriate for the
selected device. Available devices are:
ps For PostScript printers and previewers
dvi For TeX dvi format.
X75 For a 75dpi X11 previewer.
X100 For a 100dpi X11 previewer.
ascii For typewriter-like devices.
ascii8 For typewriter-like devices. Unlike ascii, this device is 8 bit
clean. This device is intended to be used for codesets other
than ASCII and ISO-8859-1.
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).
nippon For typewriter-like devices using the Japanese-EUC character
set.
lj4 For an HP LaserJet4-compatible (or other PCL5-compatible)
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.
The grog command can be used to guess the correct groff command to use
to format a file.
-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 postprocessor.
-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 spooler for printing. The command used for
this is specified by the print command in the device description
file (if not present, -l has no effect).
-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. If there is no print
command in the device description file, -L is ignored.
-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 -printCommand 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 disable the following
troff requests: .open, .opena, .pso, .sy, and .pi. For security
reasons, safer mode is 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).
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 [Toc] [Back]
A colon separated list of directories in which to search for
macro files in addition to the default directories. See
troff(1) for more details.
GROFF_TYPESETTER [Toc] [Back]
Default device.
GROFF_FONT_PATH [Toc] [Back]
A colon separated list of directories in which to search for the
devname directory in addition to the default one. See troff(1)
for more details.
GROFF_BIN_PATH [Toc] [Back]
This search path, followed by PATH, will be used for commands
executed by groff. If not set, `/usr/bin' is prepended to PATH.
GROFF_TMPDIR [Toc] [Back]
The directory in which temporary files will be created. If this
is not set and TMPDIR is set, temporary files will be created in
that directory. Otherwise temporary files will be created in
/tmp. The grops(1) and refer(1) commands can create temporary
files.
/usr/share/groff/1.17.2/font/devname/DESC
Device description file for device name.
/usr/share/groff/1.17.2/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.
To print the man page foo.1 to the standard output using the latin-1
output device and less as the pager, the following command can be used:
groff -mandoc -Tlatin1 foo.1 | less
Alternatively, you can say
groff -m mandoc -Tlatin1 foo.1 | less
