shutdown -P +3 should work.

-P means power off. You can alternatively use -r to reboot. You can use +3 to shutdown in 3 minutes, or "now" to happen right now.

You can use the shutdown command + option like below.
$ sudo shutdown -h +3

I looked it up and it seems the -h and -P commands do the same thing.
