Groups in Linux

All Linux operating systems are designed as multi-user operating systems.

This means that they provide the capabilities and related tools to create and handle multiple users within a system. One such tool is user groups. A user group is simply a collection of users.

Ubuntu list group members

It is handy when a system administrator wants to deal with multiple users simultaneously (especially for handling permissions). We define a rule for the group and it automatically applies to all its member users.

Syntax:

$ sudo useradd <username>

When a new user is created, a new group with the same name is created and the user is added to it.

This group is called the primary group of the user. For example, we create a user named "demoUser3" in the following screenshot from the terminal:

sudo groupadd demo_group
sud
