emulate nroff command with groff
[−Tname] [file ...]
−v | −−version
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.
−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.
The default device for
groff. If not set (which is the normal case), it
defaults to ’ps’.
A colon separated list of
directories in which to search for the groff
executable before searching in PATH. If unset,
’/usr/bin’ is used.
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
