I don’t have a lot of time, but I’m in a generous mood and want to help all the returds out there try to climb out of whatever intellectual mire their lives inhabit.
Here’s a quick and easy command for you to do.
Open a terminal emulator.
Either become root or use sudo with the follow command
So either type
su and then enter, and type in your root password when asked, then type
shutdown -h now , and immediately follow that with enter.
If you’re using sudo it would be,
sudo shutdown -h now, followed by hitting enter, then entering your user password and hitting enter again.
Whatever you do! Do not, and I repeat, DO NOT!!!! Do anything with your computer until you read my next how-to that I’ll post shortly. It’s far too dangerous to, trust me!
Hope that helps, returds…..
Keep your stick on the ice…

Thanks for this useful command, which efficiently brings the box in an energy saving mode, thus saving The Planet.
Perhaps hitting a password might be tiring, and one should configure (sorry, I have not sudo’s manual at hand) “sudo” to work the Kaella way (without password).
Or one should have only one user,” root”.
Have a nice day….
