I want to write a perl script to perform the below steps in scripts.

So.. what have your attempted to do? I'm seeing a disturbing pattern begin to emerge in your posts with respect to what you ask. This is not a code writing service.

If you start writing code and something blows up I and many other Monks here will be glad to help you sort it all out.

I noticed you just joined the Monastery today. Welcome aboard. Here are a few links for you to check out:

• An Intro To Perl Monks
• Welcome to the Monastery
• How (not) to ask a question
• How to RTFM

If you follow the philosophies documented in those pages you'll have a much better experience at Perl Monks.

Again, welcome aboard
