Scheduling a shutdown

To shutdown run the command:

sudo shutdown -P +60

That will wait 60 mins before starting the shutdown sequence.

You could do:

sudo shutdown -P 1:00

to shutdown at 1 AM and

sudo shutdown -P now

to shutdown now.

A message is broadcast to all terminals to warn about the shutdown.

Cancel a pending shutdown

After, starting a shutdown, if the time argument is not "+0" or "now", you can use:

sudo shutdown -c 

to cancel the scheduled shutdown.
