Shutdown and Standby in OS X

I have been looking for ways to put OS X to sleep and switch it off on a timer.

I am a fan of listening to radio while I go asleep, but not that keen on having it on throughout the night.

I couldn't find a decent app to do the job, but surprise surprise the classic Unix commands are in OS X.

So, you want to shutdown the computer in 60 minutes?

Type:

shutdown -h +60

into the terminal.

Want to put it to sleep in 30 minutes?

Type:

shutdown -s +30
