It's common, when writing in Perl, to look for functions or Modules rather than methods. They are part of classes, and usually (although not mandatory) they are applied to objects.

Two great starting points than can help you expanding your Perl knowledge, with respect to functions and modules, are CPAN and this site istelf :-) Try for example a Super Search or the Library or the Perl FAQ, or the great Tutorials...

As usual, There's More Than One Way To Do It!

Happy searching!
