lsof?

[Robert L. Harris]

OK,
  I've gotten a great response from you guys.  Definitely blows away the
2 other perl lists I'm on, and the answers are nice, clean and consice,
even my spelling is pretty rotten.

  I have another one for you.  In the same script I need to do something
like "lsof -i | grep <port>" to find out what process is  using a port,
or possibly an IP.  I can't find an "lsof" module, so I'm hoping someone
may know something similar.

Thoughts?
  Robert
