Help: grep
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.
