There is the perldoc tool installed with your Perl, and also the perlfaq online. Searching for your keywords yields good explanations of how to do things:> perldoc -q unique
How can I get the unique keys from two hashes?
How can I remove duplicate elements from a list or array?
> perldoc -q sort
How do I sort an array by (anything)?
