NAME¶
nroff - emulate nroff command with groff
SYNOPSIS¶
nroff |
[-CchipStUvwW] [-dcs] [-Mdir]
[-mname] [-nnum] [-olist]
[-rcn] [-Tname] [file ...] |
DESCRIPTION¶
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.
ENVIRONMENT¶
- 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.
NOTES¶
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.
