You can use rindex to find the index of the rightmost character of string, which you could then modify with substr, but what you really want is File::Basename, it's part of the standard distribution.

update: Indeed, Aigherach is right about the the fact that rindex takes a substring, but that is not germane to the discussion. If you're trying to identify the extension, that probably means you're looking for the rightmost dot in a string.

substr( $s, 0, rindex( $s, '.' )); # the part before the dot
substr( $s, rindex( $s, '.' ) + 1); # the part after the dot

But that has portability considerations, and as such is dealt with by fileparse from the File::Basename module.
