hg grep [OPTION]... PATTERN [FILE]...

search for a pattern in specified files and revisions

Search revisions of files for a regular expression.

This command behaves differently than Unix grep. It only accepts Python/Perl regexps. It searches repository history, not the working directory. It always prints the revision number in which a match appears.

By default, grep only prints output for the first revision of a file in which it finds a match. To get it to print every revision that contains a change in match status ("-" for a match that becomes a non-match, or "+" for a non-match that becomes a match), use the --all flag.

Returns 0 if a match is found, 1 otherwise.
