The
nroff
script emulates the
nroff
command using groff.
Only
ascii,
ascii8,
latin1,
utf8,
nippon,
and
cp1047
are valid arguments for the
-T
option.
If an invalid or no
-T
option is given,
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
-C,
-i,
-n,
-m,
-o,
and
-r
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
shows the version number.
