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 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-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 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.
-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

-i
-C

-Wname
-mname

-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.
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.
PATH The search path for commands executed by groff.
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_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.
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
