G'day ikhan,

Welcome to the Monastery.

"I am new to Perl and need to ramp up in a hurry."

I suggest you read "perlintro -- a brief introduction and overview of Perl". There may be sufficient information there to write your program: it certainly covers all the areas it looks like you need. Each section has links to further documentation: so follow them for more details as required.

When you post code or data here, please wrap it in <code>...</code> tags. Unfortunately, by posting your data as plain text, we've got no idea what the file structure looks like. This makes it difficult to suggest a solution. I'll take a punt and point you to the examples in "perlop: Range Operators" — I really am just guessing.

I suspect you may have given us enough information: it's just not in useable format. "How do I post a question effectively?" gives more details about this. "How do I change/delete my post?" tells you how to fix it.
