You could try the OpenBSD man pages. One of OpenBSD's must-haves is good documentation. If I'm looking for an example and the Linux man doesn't have one, I'll often google for "openbsd man xxxx".
Of course, watch out for differences in the utility. OpenBSD (usually) won't have any GNU extensions, for example.
