People new to Perl should get a book. Seriously. Really, a forum can never measure up to a book for the basics. This item is relatively basic (and indeed introductory), thus is undoubtedly covered in the Llama or Camel books by O'Reilly -- both excellent references.
If we answer this, and then answer "what is a semicolon used for", and so on, we end up writing a book ourselves. Please, find some suitable documentation and try to solve your problem on your own. When you gain some basic skill, and the knowledge of what the language is properly called (Perl), then come back to us.
So, as nicely as possible ... RTFM.
