A regex is a regex, but a regex search is not a regex match. I don't know that Perl provides both, and if it does I don't recall how they're differentiated. Other applications do. Python, for instance differentiates them thusly: http://www.python.org/doc/current/lib/matching-searching.html Find requires a "match" like Python's, rather than a "search" like perl or grep.
