nroff - emulate nroff command with groff
[-CchipStUvwW]
[-CchipStUvwW] [-dcs] [-d] [-Mdir] [-M] [-mname] [-m] [-nnum] [-n] [-olist]
[-o] [-rcn] [-r] [-Tname] [-T] [file~...] --help -v | --version
The
nroff script emulates the nroff command using groff. Only ascii, latin1,
utf8, and cp1047 are devices accepted by nroff to select the output encoding
emitted by grotty, groff’s TTY output device. If neither the GROFF_TYPESETTER
environment variable nor the -T command line option (which overrides the
environment variable) specifies a (valid) device, nroff checks the current
locale to select a default output device. It first tries the locale program,
then the environment variables LC_ALL, LC_CTYPE, and LANG, and finally
the LESSCHARSET environment variable.
The -h and -c options are equivalent
to grotty’s options -h (using tabs in the output) and -c (using the old output
scheme instead of SGR escape sequences). The -d, -C, -i, -M, -m, -n, -o, -r, -w,
and -W options have the effect described in troff(1)
. In addition, nroff
silently ignores the options -e, -q, and -s (which are not implemented in
troff). Options -p (pic), -t (tbl), -S (safer), and -U (unsafe) are passed to
groff. -v and --version show the version number, --help prints a help message.
- GROFF_TYPESETTER
- The default device for groff. If not set (which
is the normal case), it defaults to ‘ps’.
- GROFF_BIN_PATH
- A colon separated
list of directories in which to search for the groff executable before
searching in PATH. If unset, ‘/usr/bin’ is used.
This shell script is
basically intended for use with man(1)
. nroff-style character definitions
(in the file tty-char.tmac) are also loaded to emulate unrepresentable glyphs.
