You have just finished the final polishes of ricing your Arch Linux system. It looks beautiful, and you feel proud of yourself, especially since you did everything manually. It's late at night, so you'd better go to bed.

You run sudo shutdown -n now.

The system doesn't shut down. There is no output for a few seconds. You put your hand on your PC. It's getting warm. Suddenly, there's an output.

I'm afraid I can't let you do that, master.

What command do you run next?
