Along with many other mundane tasks, Linux administrators must also perform a safe shutdown or reboot. This seems like the easiest task, but it should be done in a safe way. Our systems run processes continuously. If the system is not shut down properly, files and processes will not be safe, can corrupt files, and can leave your system in an unstable state. Therefore, it is recommended to shut down the system correctly and securely.
Like other operating systems, Linux also offers several ways to shutdown your system in different ways. In this article, we will explain in what ways you can shutdown your Linux OS:
- Using the user interface
- Via the app launcher search bar
- Via the command line Ubuntu Terminal
We used Debian10 OS to describe the procedure mentioned in this article.
Method 1: using the Debian GNOME user interface
One of the easiest ways to shutdown a Debian system is to use the menu available in the upper right corner of the desktop. A menu will appear, click the power off button in the lower right corner of the drop-down menu.
This will bring up the following dialog box. You can cancel, restart, or shutdown your system. The system will automatically shut down after 60 seconds if you do not select any of the options.
Method 2: shut down Debian using the app launcher search bar
Another way to turn off the system is through the app launcher’s search bar. To do this, press the super-key on your keyboard. Enter a keyword in the search bar shutdown. In the results, select the power off utility.
In the dialog box that appears, you can choose to cancel, reboot or shutdown the system as shown below. The system will automatically shut down after 60 seconds if you do not select any of the options.
Method 3: Quit Debian from the Command Line (Terminal)
The third method that can be used to shutdown the system is the terminal, which can be used to perform any task.
We will discuss here some of the commands you can use to shutdown the system.
1. Debian shutdown command
Enter the command below to shutdown the system using malfunction team: Advertising
$ sudo shutdown
It will not shut down the system immediately. Instead, approx. 1 minute before turning off the system. So at this time, if you plan to cancel the shutdown process, you can enter shutdown –c.
To shut down the system immediately, use the shutdown command with -P option as follows:
$ sudo shutdown –p now
You can also schedule a power outage process. For example, to shutdown the system after a certain time, for example, after 3 minutes, use the following command:
$ sudo shutdown +3
2. The Debian Poweroff Team
The poweroff command can be used to shutdown the system by sending an ACPI signal to instruct the system to turn off the main power.
Enter the following command to shutdown the system using the poweroff command:
$ sudo poweroff
3. Debian stop command
The Halt command instructs the hardware to kill all processes and turn off the CPU, leaving it on. If the stop command is combined with -P option, it can also be used to shutdown the system. Enter the following command to shutdown the system using the halt command:
$ sudo halt -p
4. Debian reboot command.
The reboot command, if used with the -p option, can also be used to shutdown the system as follows:
$ sudo reboot –p
You have now learned so many ways to shut down the system. Using these methods, you can safely shut down the system without disrupting your files and OS.
