You can get your computer to shut down at some point in the future with the “shutdown” command. Add “-t xxx” to shut down with xxx being the number of seconds (from 0 to 315,360,000, which is ten years) and “-f” to force close any ‘you’ve got unsaved work’ dialog boxes. So if you wanted to shut your computer down in 636 seconds you would type “shutdown -f -t 636”.
