Ubuntu was originally a terminal-based operating system, but over time Linux slowly introduced the graphical user interface to its operating system. Nowadays, GUI methods are the only way to solve many problems with the operating system. We’ll show you some cool methods to shut down your system in Ubuntu like a pro!
Ubuntu, like all other operating systems, offers several ways to shut down. These include such simple methods as clicking a button or passing commands to the system via a terminal. The commands shown in the tutorial have been tested on Ubuntu 22.04 and Ubuntu 20.04.

You can make a decision within 60 seconds. After 60 seconds the system will shut down automatically.
