Thank you to everyone. This has been an informative experience. It all started because I ran the script I created and somehow it took the text file I was reading from and emptied it which I didn't notice. So I ran the script again without any errors but without any returns either. So I thought the script was bad which it was but I have since fixed. But since I didn't know exactly what the script was doing I wrote a smaller try script which is the one we are talking about. It returned no errors but no results either since I was still working with the null text file. So I searched the internet and found the site that suggested the single quotes and so here we now are.
Installing Perl::Critic was fun since I had to find and install numerous modules to get it past the make test. Is there a way to find all the dependencies before I try to install a module from CPAN?
