Article Title: how to disable a specified user account in Linux. Linux is a technology channel of the IT lab in China. Some basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source are available in today's linux releases, and 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, 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.
