Perl tutorials for an advanced level developer

Perl is a nice script language which is easy to use. It is originated as a Unix scripting language and has been improved with a lot of new features from shell scripting, C, etc. Perl is very powerful for text processing.

For an experienced developer, the useful tutorial would be a quick introduction of the language, but not in great detail. A new programming language is nothing more than its data types, conditionals, loops, file i/o, some functions and some tricky use cases.

Here is a good introduction tutorial that are helpful for me, and hopefully useful for you.

If you want someone to read your code, please put the code inside <pre><code> and </code></pre> tags. For example:
String foo = "bar";
