field seperators eh? I'm not sure how to do those, are those the things liek this
[0-9]{1,5}? The squiggly brackets?

And the head and tail, I threw in for fun because I was trying to see if I could make my pipe even longer and still work. The only thing I'm really concerned about is the grepping the numbers part, I don't seem to get all of them. If the squiggly's are field seperators I'll try them.
