[root@localhost /] # useradd # create user is the user name

[root@localhost /] # passwd # set the password for the user

Change the password of user . New password: * *

When the password is set, prompt "passwd: all authentication tokens have been updated successfully." Indicating that the password has been set successfully

2. Check the directory of some information about the user.

3. Delete a user

If you use the userdel command to delete the user, you cannot delete all the information of the user, just delete the information of the account and group in the four files / etc/passwd, / etc/shadow, / etc/group/, / etc/gshadow. By default, a user account is created, which creates a home directory and a user mailbox (named after the user name in the / var/spool/mail directory)

[root@localhost /] # userdel

[root@localhost /] # cat / etc/passwd | grep

[root@localhost /] # cat / etc/shadow | grep

[root@localhost /] # cat / etc/group | grep

[root@localhost /] # cat / etc/gshadow | grep

[root@localhost /] # find /-name ""

The next time you create a user, it appears:

The error is reported in the image above, so you will report an error when you create the user account again, which means that the files or directories related to the user have not been deleted completely before.

Then use the find command to see that the user-related files have been deleted.
