Description
gnroff formats documents written in the groff(7) language for type‐
writer-like devices such as terminal emulators. GNU nroff emulates the
AT&T nroff command using groff(1). gnroff generates output via
grotty(1), groff's terminal output driver, which needs to know the
character encoding scheme used by the device. Consequently, acceptable
arguments to the -T option are ascii, latin1, utf8, and cp1047; any
others are ignored. If neither the GROFF_TYPESETTER environment vari‐
able nor the -T command-line option (which overrides the environment
variable) specifies a (valid) device, gnroff consults the locale to se‐
lect an appropriate output device. It first tries the locale(1) pro‐
gram, then checks several locale-related environment variables; see
section “Environment” below. If all of the foregoing fail, -Tascii is
implied.
The -b, -c, -C, -d, -E, -i, -m, -M, -n, -o, -r, -U, -w, -W, and -z op‐
tions have the effects described in troff(1). -c and -h imply “-P-c”
and “-P-h”, respectively; -c is also interpreted directly by troff. In
addition, this implementation ignores the AT&T nroff options -e, -q,
and -s (which are not implemented in groff). The options -k, -K, -p,
-P, -R, -t, and -S are documented in groff(1). -V causes gnroff to
display the constructed groff command on the standard output stream,
but does not execute it. -v and --version show version information
about gnroff and the programs it runs, while --help displays a usage
message; all exit afterward.
Exit status
gnroff exits with error status 2 if there was a problem parsing its ar‐
guments, with status 0 if any of the options -V, -v, --version, or
--help were specified, and with the status of groff otherwise.
Environment
Normally, the path separator in environment variables ending with PATH
is the colon; this may vary depending on the operating system. For ex‐
ample, Windows uses a semicolon instead.
GROFF_BIN_PATH
is a colon-separated list of directories in which to search for
the groff executable before searching in PATH. If unset,
/usr/bin is used.
GROFF_TYPESETTER
specifies the default output device for groff.
LC_ALL
LC_CTYPE
LANG
LESSCHARSET
are pattern-matched in this order for contents matching standard
character encodings supported by groff in the event no -T option
is given and GROFF_TYPESETTER is unset, or the values specified
are invalid.
Files
/usr/share/groff/1.23.0/tmac/tty-char.tmac
defines fallback definitions of roff special characters. These
definitions more poorly optically approximate typeset output
than those of tty.tmac in favor of communicating semantic infor‐
mation. nroff loads it automatically.
Notes
Pager programs like more(1) and less(1) may require command-line op‐
tions to correctly handle some output sequences; see grotty(1).
