  1. use strict; and use warnings; will catch & tell you about a lot of potential errors if you let them
  2. Without chomp $port will still have a newline at the end of the string, which will be included in any match attempt.
  3. Why do you grep and then do additional filtering in Perl, when you can do it all in Perl?
