User Management in Linux

Adding and removing users on a Linux system is crucial for system administration. Typically, you start with just the root account, which has full control but can be risky. It's better to create standard users (with no admin rights) for common tasks. In order to execute commands with superuser privileges, you can either log in as a root user (sudo su , not recommended) or use sudo with your commands (recommended).

To perform admin tasks, Ubuntu has a tool called sudo, allowing you to run commands as other users, including administrators.

Create a New User.

You can use the useradd command to add a new user to the system.
