Linux to see which user groups are available: 1, log in to the linux system, right-click in the blank space of the linux desktop, select "Open Terminal"; 2, in the open terminal window, enter and execute the "cat / etc/group" command to display the relevant information of all user groups.

The operating environment of this tutorial: Red Hat Enterprise Linux 6.1 system, Dell G3 computer.

A user group is a logical collection of users with the same characteristics. To put it simply, sometimes we need to make multiple users have the same permissions, such as viewing and modifying a file. One way is to authorize multiple users to access files separately. If there are 10 users, you need to authorize 10 times. What if there are 100, 1000 or more users?

Obviously, this method is not very reasonable. The best way is to set up a group that has permission to view and modify the file, and then put all users who need to access the file into this group. Then all users have the same permissions as the group, which is the user group.

Grouping users into groups is a means to manage users and control access rights in Linux systems. By defining user groups, many programs simplify the management of users.

So how does linux view all user group information

To view the steps:

1. Open the terminal window

Log in to the linux system, right-click in the space of the linux desktop, and select "Open Terminal"

2. Enter the cat / etc/group command in the terminal window, and enter to view the relevant information of the user group.
