Single quoting and character classes are all very well if you're dealing with test data, but i think we can assume you're not really going to be testing whether two strings you just typed in match. In the general case, if you want to find out whether $var2 is contained in $var1, and $var2 might contain something that will be unhelpfully interpolated, use this: $match if $var1 =~ /\Q$var2\E/;\Q..\E is a special case of the quotemeta function, which automatically escapes non-alphanumerics (but not $ or @, so you still get variable interpolation). Not the first time this has come up, by the way. Reading perlre will help. update: followed own sanctimonious advice, read perlre, changed description of quotemeta :( In reply to Re: matching the + character
