man nroff (Commandes) - emulate nroff command with groff
NAME
nroff - emulate nroff command with groff
SYNOPSIS
nroff
[ file ... ]
DESCRIPTION
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.
ENVIRONMENT
- 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), so warnings are suppressed. nroff-style character definitions (in the file tty-char.tmac) are also loaded to emulate unrepresentable glyphs.
