Precautions before Deleting a User Account

Before proceeding with user deletion, it is important to take a few precautions to ensure a smooth and error-free process. Firstly, make sure you are logged in as a root user or have the necessary sudo privileges. This will grant you the required administrative permissions to delete user accounts.

Step 1: Logging in as a Root User or Using ‘sudo’ Command
