Hello and welcome to the monastery!

This question has been answered very often, so I'm going to give you some hints on how to search more efficiently:

• In the top left corner of the page, there is a text entry with a button labeled "Search" besides it. Entering your question there often helps you to find interesting nodes.
• In some cases that is not enough, as the normal search only searches the node titles and not the node content. In such cases, Super Search is the next step to use.
• If even Super Search fails you, you might want to use Google to search, as demonstrated by thepen.
• In other situations, simply looking at what http://search.cpan.org has to offer for File Copy is often worth a look.
• If that still fails you, you might still search with Google, but this time not restricted to Perlmonks.

I hope these pointers help you with your next search. It is also often more welcomed to be more elaborate in your question and to show what you have already tried as well.
