The following command causes an immediate system sleep
pmset sleepnow
Trying to shutdown system with pmset
$ pmset shutdown
Usage: pmset <options>
See pmset(1) for details: 'man pmset'
Experiment with shutdown command
$ shutdown -h now
shutdown: NOT super-user
$ sudo shutdown -h now
Password:
So each time to shutdown system, I should enter a password to use the superuser.
Could it be possible to shut down with ‘pmset’?
