3 Steps to Remove a User from a Group using the gpasswd Command
In my Ubuntu, there is a user by the name of “walid” and he is in a group named “mygroup”. Now I will remove user “walid” from the “mygroup” group using the gpasswd by the following three steps.

In this step, I will use the gpasswd to remove the user “walid” from group “mygroup”.
