groff

GNU replacement for the troff and nroff typesetting utilities. More information: https://www.gnu.org/software/groff.

• Format output for a PostScript printer, saving the output to a file:

groff path/to/input.roff > path/to/output.ps

• Render a man page using the ASCII output device, and display it using a pager:

groff -man -T ascii path/to/manpage.1 | less --RAW-CONTROL-CHARS

• Render a man page into an HTML file:

groff -man -T html path/to/manpage.1 > path/to/manpage.html

• Typeset a roff file containing [t]ables and [p]ictures, using the [me] macro set, to PDF, saving the output:

groff -t -p -me -T pdf path/to/input.me > path/to/output.pdf

• Run a groff command with preprocessor and macro options guessed by the grog utility:

eval "$(grog -T utf8 path/to/input.me)"
