How to Delete/Remove Users in Linux (userdel Command)

Linux is a multi-user system, which means that more than one person can interact with the same system at the same time. As a system administrator, you have the responsibility to manage the system’s users and groups by creating new users and assign them to different groups .

Occasionally, you might need to delete a user account. Perhaps because the user moved away from the organization, or it was created for a specific service that no longer runs on the system.

In Linux, you can delete a user account and all its associated files using the userdel command.

This tutorial covers the userdel command and its options.

userdel Command Syntax

The syntax for the userdel command is as follows:

userdel [OPTIONS] USERNAME

To delete users using the userdel command, you need to be logged in as root or a user with [sudo](https://linuxize.com/post/sudo-command-in-linux/) access.
