How to disable a user account in linux-general Linux technology-Linux technology and application information. For details, refer to the following section. In today's linux releases, users' passwords are stored in/etc/shadow.

Prohibit a user. You only need to add * Before the encrypted password in the second column of the corresponding user in shadow.

This user cannot log on to the machine. If you re-enable this user, remove this.

If the system has a usermod program, you can also use usermod-L to lock the user. The principle is the same, but what you insert is! No.

Userdel can delete a user, and-r can delete the user's home file.

However, this is generally not recommended.

The reason is that, for example, if the id of user A is 533, after deletion, 533 can be assigned to user B next time. In this case, there may be files left before A. The owner is 533, which will be owned by B. Obviously this is unreasonable.
