What does the deluser command do?

The deluser command is specifically designed to remove a user account from the Linux system. When executed, it not only deletes the user's account but can also be configured to remove the user's home directory and associated files, depending on the options used with the command. This makes it an efficient tool for system administrators to manage user accounts and maintain system security by ensuring that unused or unnecessary user accounts are properly removed. The functionality of deluser is vital for maintaining a clean user environment and for compliance with security policies that require user accounts to be deactivated when no longer needed.
