An in-depth discussion of the restart commands of Linux systems

Linux system is an open source operating system that is widely used in servers, embedded devices, personal computers and other fields. In the process of using the Linux system, it is often necessary to restart the system to solve some problems or to make the system take effect and update the configuration. This article will delve into the restart command of the Linux system and provide specific code examples to help readers better understand and apply relevant knowledge.

In Linux systems, the restart operation can be implemented in a variety of ways, among which the most commonly used commands are reboot and shutdown. Next we will introduce in detail the usage of these two commands and their role in the restart process.

rebootCommand

reboot command is the simplest and most direct restart command, just enter ## in the terminal #reboot can trigger a system restart. This command immediately shuts down the system and then restarts it. The following is a sample code:

reboot

Copy after login

After executing the above code, the system will perform a restart operation, and the system will restart after prompting the user for confirmation.

shutdownCommand

#shutdown command can also play a role when restarting the system, and the restart can be flexibly controlled by matching parameters time and manner. Commonly used parameters include -r which means restarting, and -h which means shutting down. The following is a sample code:

shutdown -r now

Copy after login

After executing the above code, the system will restart immediately. Among them,

-r means restarting, and now means executing immediately. If you want to delay the restart operation, you can use the parameter plus the delay time, for example shutdown -r 5 means restart after 5 minutes.

In addition to using the command line directly, the Linux system can also be restarted through the graphical interface. In the desktop environment of most Linux distributions, a restart button is provided, and the system restart operation can be triggered by simply clicking the button.

To summarize, through the introduction in this article, readers should have a deeper understanding of the restart command of the Linux system. In the actual application process, appropriate commands and parameters can be selected according to specific needs to implement the restart operation. I hope that readers can use the help of this article to operate the Linux system more skillfully and improve work efficiency.
