Something like
should do the trick. In this code fragment I'm looking for a real period, followed by any number of word characters, followed by the end of the string. I put that in brackets so that I can grab it as $1 later on. This of course makes the assumption that your definition of a file extension is the group of characters to the right of the last period in a file name .. so the file extension of "foo.bar.baz" would be "baz". Your code should also handle the situation where there are no periods in the filename. ps I highly recommend reading Programming Perl (Third Edition) by Wall, Christiansen & Orwant, published by O'Reilly.
