Just how much do you know now? If this is first time you've exposted yourself to Perl, you probably better start with the usual list of recommendations: read Learning Perl; the introductory Tutorials on this site, etc. etc. because, otherwise, you're just asking us to hand you a solution, rather than (as is the ethic here) helping your learn.

OTOH, if you've done some homework on Perl, and have become stuck on some particular aspect of your problem ... and we know what you've done so far and what your sticking point is (hint, hint: post code, error messages and -- if relevant -- narrative explanation of where output fails to satisfy you).
