If, like me, you've ever been annoyed at people just saying to grep the output of ifconfig for inet, and the likes, to get the assigned IP address of a network interface.
I got annoyed one time too many.

May or may not also work on for example the *BSDs, but should definitely work on any modern typical-userland Linux.
