Help: grep

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

search for a pattern in specified files

Search the working directory or revision history for a regular expression in the specified files for the entire repository.

By default, grep searches the repository files in the working directory and prints the files where it finds a match. To specify historical revisions instead of the working directory, use the --rev flag.

To search instead historical revision differences 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 --diff flag.

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

If no FILEs are specified and the --rev flag isn't supplied, all files in the working directory are searched. When using the --rev flag and specifying FILEs, use the --follow argument to also follow the specified FILEs across renames and copies.

Template:

The following keywords are supported in addition to the common template keywords and functions. See also 'hg help templates'.

change
String. Character denoting insertion "+" or removal "-". Available if "--diff" is specified.
lineno
Integer. Line number of the match.
path
String. Repository-absolute path of the file.
texts
List of text chunks.

And each entry of "{texts}" provides the following sub-keywords.

matched
Boolean. True if the chunk matches the specified pattern.
text
String. Chunk content.

See 'hg help templates.operators' for the list expansion syntax.

Returns 0 if a match is found, 1 otherwise.
