In contrast to ``grep``, ``string``\ s `match` and `replace` default to glob-mode. If set to regex-mode, they use PCRE regular expressions, which is comparable to ``grep``\ s `-P` option. `match` defaults to printing just the match, which is like ``grep`` with `-o` (use `--entire` to enable grep-like behavior).
