This is a bad idea for anything other than throwaway scripts... it requires building a full regex everytime (from $two). You *MUST* use quotemeta() on $two to make it safe, other any regex characters will apply - which is VERY UNSAFE. Perl might be fast, but best not making it work harder than is needed. Unsafe, why? ------------ What if $two contained: "((((.*)*)*)*)*a$" that has exponential runtime :( BUT, what if $two contained: "?{system('rm -rf /')}" that'd REALLY wreak your day - as you reach for the most recent backup tapes...
