A user group is a logical collection of users with the same characteristics. To simply understand, sometimes we need to allow multiple users to have the same permissions, such as permissions to view or modify a certain file. One way is to authorize file access to multiple users separately. If there are 10 users, authorization is required. 10 times, what if there are 100, 1000 or even more users?
Obviously, this method is not reasonable. The best way is to create a group that has permission to view and modify this file, and then put all users who need to access this file into this group. Then, all users have the same permissions as the group, which is the user group.
Grouping users is a means of managing users and controlling access rights in Linux systems. By defining user groups, many programs simplify user management.
