What about books? Looking at the index of Learning Perl, (files entry) I see a reference to File::Copy, in an appendix with some other important modules.

And the Perl Cookbook? Recipe 9.3: Copying or Moving a File.

Searching for things requires a bit of common sense and some imagination. If an online search doesn't yield useful information, ask yourself: "How can I ask this question in another way?". With books, learning to use the index is very important.

I try to use local resources first (Programming Perl and the Cookbook are always within reach) and failing that, I use Google and CPAN. Most of the time that answers my needs.
