Often I need to find my external IP address, warranting a trip to whatismyip.com. To speed this up I created a LaunchBar action that fetches the info for me. It’s a simple wrapper around a one-liner that requests and parses the IP address reported by Dyn.
curl --silent http://checkip.dyndns.org/ | grep --extended-regexp --only-matching '\d+\.\d+\.\d+\.\d+'
This is useful on its own as a shell command, but when available as part of your LaunchBar workflow it becomes even handier.1
