NROFF(1)                             General Commands Manual                             NROFF(1)

NAME
       nroff - use groff to format documents for TTY devices

SYNOPSIS
       nroff [-CchipStUv] [-dcs] [-Mdir] [-mname] [-nnum] [-olist] [-rcn] [-Tname] [-Wwarning]
             [-wwarning] [file ...]

       nroff --help

       nroff -v
       nroff --version

DESCRIPTION
       nroff formats documents written in the roff(7) language for typewriter-like  devices  such
       as terminal emulators.

       GNU  nroff  emulates  the  traditional Unix nroff command using groff(1).  nroff generates
       output via grotty(1), groff's TTY output device, which needs to know the character  encod-
       ing  scheme used by the terminal.  Consequently, acceptable arguments to the -T option are
       ascii, latin1, utf8, and cp1047; any others are ignored.  If neither the  GROFF_TYPESETTER
       environment variable nor the -T command-line option (which overrides the environment vari-
       able) specifies a (valid) device, nroff consults the locale to select an appropriate  out-
       put  device.  It first tries the locale(1) program, then checks several locale-related en-
       vironment variables; see "ENVIRONMENT", below.  If all of the foregoing fail,  -Tascii  is
       implied.

       Whitespace is not permitted between an option and its argument.  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 ignores -e, -q, and  -s
       (which  are not implemented in troff).  The options -p (pic), -t (tbl), -S (safer), and -U
       (unsafe) are passed to groff.  -v and --version show  version  information,  while  --help
       displays a usage message; all exit afterward.

ENVIRONMENT
       GROFF_TYPESETTER
              specifies the default output device for groff.

       GROFF_BIN_PATH
              is  a  colon-separated  list  of  directories in which to search for the groff exe-
              cutable before searching in PATH.  If unset, /usr/bin is used.

       LC_ALL
       LC_CTYPE
       LANG
       LESSCHARSET
              are pattern-matched in this order for standard  character  encodings  supported  by
              groff in the event no -T option is given and GROFF_TYPESETTER is unset.

NOTES
       Character definitions in the file /usr/share/groff/1.22.4/tmac/tty-char.tmac are loaded to
       replace unrepresentable glyphs.
