How to set Linux to shut down automatically

Recently I had to schedule the shutdown of my computer because I wanted to let him update the game on Steam while leaving home to work, but I would come back very late this day and the update would last a maximum of two hours.

But as I know the power of the Linux terminal I thought, "There must be some way to do this for the terminal …" and what?

Quite simple to do on top of that, let's go!

Shutting down your computer through the terminal

The really simple process, open your ends and type the following command:

sudo shutdown -h +XX

In this case the XX represents the time in minutes that the computer should shut down from the current time. For example: sudo shutdown -h +90 would cause the computer to stay on for ninety minutes more from the moment the command was given.


sudo shutdown -h XX: XX

This second case is a bit more specific, in which you can define exactly what time you want the computer to turn off, the time should be informed in 24 hour format, in this case the XX: XX represent the hours and minutes.

For example: sudo shutdown -h 16:30 this causes the computer to shut down 4:30 pm, also known as four thirty in the afternoon.

Canceling shutdown

If you have mistaken the time to set the time or shutdown time do not worry, cancel the process very simple, just use the shortcut key Ctrl + C or simply close the terminal by terminating the process.

See you next time!
