Help: grep

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

search revision history for a pattern in specified files

Search revision history for a regular expression in the specified files or the entire project.

By default, grep prints the most recent revision number for each 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.

PATTERN can be any Python (roughly Perl-compatible) regular expression.

If no FILEs are specified (and -f/--follow isn't set), all files in the repository are searched, including those that don't exist in the current branch or have been deleted in a prior changeset.

Returns 0 if a match is found, 1 otherwise.

options ([+] can be repeated):

-0 --print0 end fields with NUL
--all print all revisions that match
-a --text treat all files as text
-f --follow follow changeset history, or file history across copies and renames
-i --ignore-case ignore case when matching
-l --files-with-matches print only filenames and revisions that match
-n --line-number print matching line numbers
-r --rev REV [+] only search files changed within revision range
-u --user list the author (long with -v)
-d --date list the date (short with -q)
-T --template TEMPLATE display with template (EXPERIMENTAL)
-I --include PATTERN [+] include names matching the given patterns
-X --exclude PATTERN [+] exclude names matching the given patterns

global options ([+] can be repeated):

-R --repository REPO repository root directory or name of overlay bundle file
--cwd DIR change working directory
-y --noninteractive do not prompt, automatically pick the first choice for all prompts
-q --quiet suppress output
-v --verbose enable additional output
--color TYPE when to colorize (boolean, always, auto, never, or debug)
--config CONFIG [+] set/override config option (use '')
--debug enable debugging output
