How do I use Perl?

Assuming you mean how do I learn to program in Perl, it is done by repeating two steps:

Read - Find a good introductory book (Learning Perl is excellent), read it through to get a feel for the language.

Write - as you're reading the book write small scripts to test out concepts as they are brought up. Then gradually build up to a larger project. If you can't think of ideas for projects, read Where the inspiration comes from ?.

Read - As you're working on the project you'll need to refer to reference material often. Programming Perl is excellent for this. Other reference materials include module documentation at CPAN, perldoc, and of course, The Monastery.

Repeat as necessary.
