Описание (Description)
nroff formats documents written in the roff(7) language for
typewriter-like devices such as terminal emulators. GNU nroff
emulates the AT&T nroff command using groff(1). nroff 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 variable nor the -T command-line
option (which overrides the environment variable) specifies a
(valid) device, nroff consults the locale to select an
appropriate output device. It first tries the locale(1) program,
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 options 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, -t, and -S are documented in
groff(1). -V causes nroff to display the constructed groff
command on the standard output stream, but does not execute it.
-v and --version show version information about nroff and the
programs it runs, while --help displays a usage message; all exit
afterward.
Статус выхода (Exit)
nroff exits with error status 2 if there was a problem parsing
its arguments, with status 0 if any of the options -V, -v,
--version, or --help were specified, and with the status of groff
otherwise.
Окружение (Environment)
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/local/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.
Файлы (Files)
/usr/local/share/groff/1.23.0/tmac/tty-char.tmac
Character definitions from this file are loaded to replace
unrepresentable glyphs.
Примечание (Note)
Pager programs like more(1) and less(1) may require command-line
options to correctly handle some output sequences; see grotty(1).
