groff

GNU replacement for the troff and nroff typesetting utilities.

=> More information.

• 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})"
