Which command is used to delete a user in Linux?

The command used to delete a user in Linux is "userdel" followed by the username. This command is part of the standard set of user management utilities available in most Linux distributions. When executed, it effectively removes the specified user from the system, along with their home directory and mail spool, if specified with the correct options.

The "userdel" command operates at a low level and interacts directly with the system’s user database. It ensures that all necessary files are cleaned up as part of the deletion process. This makes it a reliable choice for administrators needing to manage user accounts on Linux systems.

Other commands listed, while they may sound similar, do not align with the standard user management commands in Linux. For instance, "deluser" and "removeuser" are commands available in certain distributions like Debian and Ubuntu but are not universally applicable across all Linux systems. They serve as high-level wrappers around userdel but do not represent the core command for user deletion. "userdelete" is not a recognized command in Linux, further solidifying that "userdel" is the correct and standard choice for this operation.
