NAME

       nroff - emulate nroff command with groff

SYNOPSIS

       nroff [-CchipStUvwW] [-dcs] [-Mdir] [-mname] [-nnum] [-olist] [-rcn] [-Tname] [file ...]
       nroff --help
       nroff -v | --version

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.
