The first thing I notice is that your variable isn't being called correctly.


$hexval = sprintf("%x", $readline);

I hate perl, but it...

So just for clarification, you want to call a file you're creating with certain key words instead of calling your whole egrep?

So instead of

I would imagine you can just throw a prompt in there...
