Hey all- been playing around with something here... I've got an array that is populated with data given by iptables. Specifically I'm just getting the data from one of the columns, but this is my problem. First off, I've seen this node: How do I keep anything other than alphanumeric out of a variable? but would rather see something working from beginning to end.

The variable is an array, and i'm going through its elements, but the problem is that on top of the data I want (the ip addresses), it's also saving the return character, essentially it adds a '\n' on the end of every element. The question is based on how do I get rid of this bugger? It's making comparing the values against other things a big pain for me. The desired result would be converting '192.168.1.1\n' to '192.168.1.1'

Thanks again!
