[thewhizkid]

I need to write a small Perl program to scan my hard disk and
list out all unique file extensions.

Can someone help me write the code ?

Thanks

I need to write a small Perl program to scan my hard disk

perldoc File::Find

and
list out all unique file extensions.

perldoc File::Basename
perldoc -q duplicate (hint: see in particular the last sentence)

Can someone help me write the code ?

What do you have so far (you didn't show us any code)? Where are you stuck?
