Actually this tutorial is a simple tutorial that many people probably already know, but I created this tutorial is not for a Senior Linux users or Linux users who are experts, but for those users who are new to linux like me.

Okay let's get started, do you already know how to add a user and group on linux? If you do not know him, let's discuss together. Before you run this command, you must be logged in as a super user. Use the command sudo su, and enter your password.

$ Sudo su

password: ****

The display of the terminal is not using $ but now use #.
