Set Automatic System Shutdown In Ubuntu

A simple command can be entered in the Terminal to schedule a time for the system to shut down.

1. Go to Applications (or Main Menu) > Accessories > Terminal.
2. Enter sudo shutdown -h +m (replace m with the number of minutes, e.g. +60).
   OR: enter sudo shutdown -h hh:mm (replace hh:mm with the time on the 24hr clock, e.g. 23:15).
3. Enter password and minimize the Terminal window.

The system will then shut down within the minutes or at the time specified. To cancel a scheduled time, enter sudo shutdown -c in the Terminal.

   Alternatively, you might want to download and install GShutdown, which is a GUI program for scheduling a time to shutdown the system.

 Note:

CompizConfig Settings Manager (ccsm), if not added yet, can be installed this way:

1. Click "Applications" (or "Main Menu"), select "Ubuntu Software Center".
2. Type ccsm into the Search box.
3. Select "Advanced Desktop Effects Settings (ccsm)" and click the "Install" button.
4. Enter the password used upon installation of Ubuntu.
