'How to make a linux pc go to sleep after a period of time?
I'm running an Arch Linux KDE PC, and I like to listen to calming music before sleeping.
What command/script that I can run on my PC to make the device go to sleep (Or shutdown) after a period of time?
Example: Shutdown in 1.5h OR Sleep in 1.5h
Solution 1:[1]
To shutdown, use the relative format (+m) and schedule a shutdown in a defined number of minutes from the time you run the command. The command syntax is:
sudo shutdown +m
For example, to shut down the system in 90 minutes, run:
sudo shutdown +90
To suspend the system after 90 minutes, run:
sleep 90m && systemctl suspend
Similar workaround for powering off the system after 90 minutes is to run:
sleep 90m && systemctl poweroff
