Groups that are used for in Linux

In Linux, a Group is just an accumulation of users. The group is basically used for administrating permissions among the number of users.

This concept of Group is used across a Unix-like operating system as a whole apart from Linux platform. A user definitely needs to belong from at least one group and it should be the user’s primary group. A user can also belong to other groups but that falls under the secondary group. Single users associated with many secondary groups and that definitely has a limit.

How does Ubuntu add users to a group

Run this command and a list of groups will appear on your screen and also show which users are assigned to the groups.

If you want to add a user to a group, just type usermod command and follow as instructed

sudo usermod  – a  -G group  username

The above-written command will replace the old group with the name of the new group and username with the name of the user.
