"I'm still having some issues to understand some parts, but i'm searching for the parts that i dont understand about Pearl Language in google."

I'd recommend looking in http://perldoc.perl.org/perl.html, using perldoc from your command line, or searching this site with Super Search before reaching for a generic search engine.

If there's anything you still don't understand, you can always ask here. If you give a link back to this thread, that will provide context for your question. Also, indicating what research you've already undertaken, and how the results of that were lacking, will get you a better answer: for instance, if you ask about X, you'll likely get replies about just X; if you say you've found X but not some specific aspect of X, you'll likely get replies about that specific aspect of X.

By the way, if you search for "Pearl", you'll find information about oysters and necklaces. :-)
