This article mainly introduces "which categories of linux users are divided into". In daily operation, I believe that many people have doubts about which categories of linux users are divided into. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the questions of "which categories of linux users are divided into?" Next, please follow the editor to study!

There are three kinds of users in the linux system, which are: 1, root (Super Admin), UID is 0, with great authority; 2, system users, UID range is "1 million 499"; 3, ordinary users, UID range is "500 million 65534".

The operating environment of this tutorial: linux5.9.8 system, Dell G3 computer.

Linux is a multi-user and multi-task operating system. In other words, the Linux system supports multiple users logging in at the same time, and different users can perform different tasks without affecting each other.

Different users have the right not to ask, and every user completes different tasks within the scope of permission. Linux realizes the operation mechanism of multi-user and multi-task through the division and management of this kind of authority.

So how many linux users are there?

Users in the linux system are divided into three categories:

The first category: root (Super Admin), UID is 0, this user has great permissions and can directly ignore many restrictions, including read and write permissions.

The second category: system users, UID is 1: 499. Usually will not be logged in.

The third category: ordinary users, the UID range is generally 500mm 65534. The permissions of such users are limited by basic permissions as well as by administrators. Note, however, that nobody is a special account with a UID of 65534. This user's permissions will be further restricted and are generally used to implement guest accounts.

At this point, the study on "which categories of linux users are divided into" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
