Hello: Let's suppose I want to parse a line from auth.log and extract the IP address (if any) to stdout. I'm assuming there is a robust way to do this using standard command-line tools ... but my brain is flailing on the exact method. Anyone have a example they'd be willing to share? Or is this a problem already solved? Hopefully, Robert Huff
