Interesting new UNIX commands/binaries in OS X Mountain Lion:
In addition to those on its well-known list of 200+ new features, OS X Mountain Lion also brings along a handful of new UNIX commands and binaries. Most are probably outside the scope of Ask Different (e.g. commands concerning Radius Authentication, Kerberos or Berkeley DB maintainance) but some of them may prove valuable to (aspiring) power users out there.
The caffeinate command is probably the most interesting of the bunch, especially if you’re already using the quite helpful Caffeine.
