NROFF(1)                   General Commands Manual                  NROFF(1)

NAME         top

       nroff - emulate nroff command with groff

SYNOPSIS         top

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

DESCRIPTION         top

       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         top

       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/local/bin’ is used.

NOTES         top

       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.
