How to add / remove a user via a terminal in Ubuntu

Of this manual you will learn how to add / delete users in Ubuntu Linux. Also, I will explain how to add a user to "sudo", but be careful, because the users of this group can execute commands with root
privileges.

How to add a user

So, to add a new user in Ubuntu, use the following command:

sudo user add username

Instead of "username" enter the name of the new user.

Create a home directory for the new user:

sudo mkdir /home/username

Now create a password for the new user:

sudo passwd username

Set the correct permissions on the home folder ofthe new user:

sudo chow nusername /home/username sudo chgrp username /home/username

All, you can now use the system from under the new user.

Issuing the root-user rights

If you need to give root-rights to the new user, then use this command:

sudo adduser username sudo

How to delete a user

To delete a user, use the following two commands:

sudo userdel username sudo rm-r/home/username/

This will remove the user from the system, as well as his home folder.

This manual is suitable for any version of Ubuntu, Linux Mint, as well as almost any other distribution.
