This article mainly introduces what Linux root user means, has a certain reference value, friends who need it can refer to it. I hope you all have a lot of success after reading this article. Let's take a look at it together.

Root exists in UNIX systems (such as AIX, BSD, etc.) and UNIX-like systems (such as Debian, Redhat, Ubuntu, etc. versions of Linux systems and Android systems), and the superuser is generally named root, which is equivalent to the system user in Windows systems.

Root is the only superuser in the system and has all the privileges in the system, such as starting or stopping a process, deleting or adding users, adding or disabling hardware, and so on.

The root user is the only super administrator on the system and has privileges equivalent to those of the operating system. Some applications that require root privileges, such as ad blocking, require root privileges. The problem is that root is more capable than the windows system administrator, enough to delete most of the entire system files, resulting in complete destruction of the system, can not be used again. Therefore, improper operation with root is quite dangerous, slight can crash, serious can not even boot. Therefore, in Unix, Linux, and Android, root is generally not recommended unless it is absolutely necessary. It's best to create a single regular user for everyday use.

Because root privileges are large, many hackers will obtain root privileges as the highest target, and even turn root into a verb, for example, I rooted the box. It means I have root privileges on this machine.

root@xs-hp:~#xs@xs-hp:~$

Note:

root xs //means user name, root is super user, xs is ordinary user @ //in xs-hp //host name ~ //current path is home directory #$ //permission flag bit, the former represents root user, the latter is ordinary user sudo + command //make ordinary user have root privileges sudo su - //switch to root user Thank you for reading this article carefully, I hope to share what Linux root user means Content is helpful to everyone, At the same time, I hope you will support me a lot, pay attention to the industry information channel, find out if you encounter problems, and find detailed solutions waiting for you to learn!
