This article mainly shows you "how to use the userdel command in Linux". The content is simple and clear. I hope it can help you solve your doubts. Let the editor lead you to study and learn how to use the userdel command in Linux.

The Linux common command userdel command is used to delete a given user, as well as files related to the user. If you do not add the option, only the user account will be deleted, not the related files.

Userdel is used to delete a given user and files related to the user

Syntax userdel (options) (parameters) option-f: force deletion of the user, even if the user is currently logged in;-r: delete all files related to the user while deleting the user. Parameter user name: the user name to delete.

For example, the userdel command is very simple. For example, we now have a user linuxde whose home directory is located in the / var directory. Now let's delete this user:

Userdel linuxde # deletes user linuxde, but does not delete its home directory and files; userdel-r linuxde # deletes user linuxde and deletes its home directory and files together; please do not easily use the-r option; he will delete all files and directories of the user at the same time, remember that if there are important files in the user directory, please back up before deletion.

There is also the easiest way, but it is a bit insecure, that is, to delete the records of the users you want to delete directly in / etc/passwd; but it is best not to do so. / etc/passwd is an extremely important file, and you may make a mistake if you are not careful.
