See How do I post a question effectively?. You have been told before. You need to wrap code and data in <code> tags so that your posts are legible and so your data does not get corrupted in display.
What have you tried? What didn't work? Post code and we'll help you debug. We aren't here to do your work for you. If this is homework, you are only hurting yourself by not doing it yourself.
Why do you want to use regular expressions? Rather that dealing with all sorts of corner cases yourself, you should probably use File::Spec, one of the core modules. In particular, see splitpath, splitdir and catpath.
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
Read Where should I post X? if you're not absolutely sure you're posting in the right place.
Please read these before you post! —
