To find your Perl version, type "perl -v" from any commandline. This will work on pretty much any system Perl can be installed onto.

As for your regex, I'll explain what you're doing. You're matching against 'W' (that's the capital letter) and '_' (underscore). You probably want a '\' (backslash) in front of the W. :-)
