Are you familiar with the Linux operating system and why it is popular in network management? Basically, Linux directly manages system hardware and resources, such as the CPU, memory, and storage.
In fact, there are a lot of advantages when you use Linux OS on your desktop. The only downturn when using the Linux OS is that it will take some time for you to get used to its important system functions. That is because most of these system functions are placed in various locations.
Is rebooting an issue with Linux?
Basically, Linux is fully able to run for years without a reboot making it is an industry-specific OS. However, that might be a bit extreme for laptop and desktop users. But for a system that may not require rebooting often, this OS has a lot of choices when you need a reboot.
Rebooting and shutting down might behave differently due to various initialization systems or command designs. A couple of concepts are vital when rebooting the Linux OS.
- There is no need to reboot your computer unless advised by a software updater or installer.
- Rebooting can be a friendly process, which allows time for applications to exit, files to save, and temporary files to be removed, among others.
What are the reboot commands in Linux?
- Click the button
You can use the most common way to reboot or shut down your OS via the power button. It is the most intuitive way for most desktop users regardless of the OS.
This can be found in different places, such as the following.
- On the system tray of the GNOME desktop
- On the GNOME Activities menu
- On the KDE desktop, it can be found in the Applications menu
The KDE power tools can be accessed by right-clicking on the desktop and selecting the Leave option.
- Use the physical button
The Linux desktop displays a power menu with options to reboot or shut down. On the GNOME desktop, open the system tray menu and click Activities, and then the Settings.
In the left column, select the Power category and in the Suspend & Power button section, you can select what you want to do with the physical power button.
- Run the systemctl command
If you are going to operate in a terminal than in a graphical user interface desktop, you may choose the reboot with a command. The processes of the init system include rebooting and powering down options.
Systemd is the init system in most modern Linux distributions. So, you can use the systectl, which is a systemd user interface that can accept options such as halt, power off, and reboot.
- Run the reboot command
This can be done from the terminal through the reboot command, which is a shortcut to the shutdown -r now command.
- Using init on systems without systemd
On Linux distributions without systemd, you can find up to 7 runlevels that your PC can understand. Different distributions can uniquely assign each mode wherein 0 initiates a halt state and 6 initiates a reboot.
Runlevel 0 powers off your computer, while runlevel 6 reboots it, using the $ sudo telinit 0 and $ sudo telinit 6, respectively.
Note that you have to consider the init configuration before using these commands to protect data from potential loss. Thus, mapping the runlevels to friendly commands can be a safer option.
