Incidentally, while you received good, general purpose answers, for the actual situation you describe Archive::Rar may be the way to go.

Update: now that I check it, I notice that it's just a wrapper around the cli util, so maybe it won't be that much of an advantage. In general however it's sensible to search CPAN for modules suitable for whatever task you're working on.
