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

    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.

      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.
