This post shows students and new users the steps to add or remove users on Ubuntu Linux. Whether you are a system administrator managing a server or a home user working at an Ubuntu desktop, adding new users to Ubuntu is something you might want to learn how to do.

By default, after installing Ubuntu Linux, the first account created during installation is the primary user of the systems. This user can perform administrative tasks as root using the sudo command.

By default, the root user account is disabled. There are no other active user accounts. Therefore, to provide exclusive access to a user, you must create an account for him or her. A service can also have an account, in cases where it needs to perform account-related tasks.

Also, for students and new users learning Linux, the easiest place to start learning is Ubuntu Linux. Ubuntu is the modern open source Linux operating system for desktops, servers, and other devices.

In Ubuntu, there are two command line tools that you can use to create a new user account: useradd and add user.

On Ubuntu Linux, the useradd The tool is a low-level utility. add user is a script that acts as a friendly interactive interface for useradd.
