7.10. The Next Step

This was just an introduction to perl's regular expressions. There is much more available functionality, and I am referring you to the following sources for more information:

• The perlsyn document.
• perlrequick (the regular expressions' quick start), perlretut (regular expressions tutorial) and perlreref (regular expressions reference).
• The perlre document. The bugs section of it says that it "varies from difficult to understand to completely and utterly opaque".
• The perlfaq6 document that deals with regular expressions.
• The book Mastering Regular Expressions by Jeffrey Friedl, published by O'Reilly and Associates.
