What does the '-h' option in the userdel command do?

The '-h' option in the userdel command is included to indicate that it does not have any effect on the account deletion process itself. When using the userdel command, its primary function is to remove a user account from the system. The '-h' option is often used to clarify that it is simply a flag that does not alter the fundamental actions of the command.

For instance, when you are deleting a user, the command will focus on the specified account, and adding the '-h' option will not change the outcome of the deletion, nor will it impact any files or processes related to that user account. The main goal with userdel is to successfully remove the user, and the inclusion or omission of this particular option does not modify that goal. This understanding is crucial for effectively managing user accounts in a Linux environment.
