groff

Typesetting program that reads plain text mixed with formatting commands and produces formatted output. It is the GNU replacement for the troff and nroff Unix commands for text formatting.

• Render a man page as plain text, and display the result:

groff -man -T utf8 {{manpage.1}}

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

groff -man -T ascii {{manpage.1}} | less

• Render a man page into an HTML file:

groff -man -T html {{manpage.1}} > {{page.html}}

• Process a roff file using the tbl and pic preprocessors, and the me macro set:

groff -t -p -me -T utf8 {{foo.me}}

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

eval "$(grog -T utf8 {{foo.me}})"
