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.

is there any way to exit the shutdown program. When I press ctrl + c after executing shutdown, it also aborts the scheduled shutdown. – Mark Evans Jun 28 '16 at 18:37

Just press Ctrl+Z, which will allow any command to run in the background – Cosine Mar 01 '17 at 04:16

Does this command override any programs that might be running at the time? – Josh Jan 19 '20 at 20:00
