I had written some scripts in Perl about 4-5 years ago. I had used Perl 5.14. It was my first programming language and I totally loved the experience. I tried to use Perl Modules wherever I could in order to avoid simply wrapping commands inside the Perl scripts. The SSH and Email Modules were my favourite because I could accomplish a lot by using them to login to the various servers and devices, collect the outputs, dump them into a text file, use regular expressions (I love Perl's Regex), filter the required parts and mail them to the team so that appropriate actions could be taken.
I am planning to get back to Perl. I am not a programmer by profession. Just a regular IT Guy. Should I start from scratch or some intermediate level book? I hope this doesn't sound like me asking here "What should I eat? Chicken or fish?" :)
If my question appears relevant, kindly guide me.
