What is true regarding the command userdel --force --remove bob? (Choose TWO correct answers.)
The command userdel --force --remove bob is used to delete the user account named bob and all its associated files. The --force option forces the removal of the user account, even if the user is still logged in.The --remove option forces userdel to remove the user's home directory and mail spool, even if another user uses the same home directory or if the mail spool is not owned by the specified user12. Therefore, options A and B are true regarding this command.
The other options are not true because:
Option C is false because the locate database is not updated by the userdel command.The locate database is updated by the updatedb command, which is usually run by cron as a scheduled job3.
Option D is false because the userdel command does not remove all files owned by bob from all mounted filesystems. The userdel command only removes the user's home directory and mail spool, and it does not search for and delete the user files located in other file systems.You have to search for and delete the files manually1.
Option E is false because the userdel command does not delete the group with the same name as the user, unless the USERGROUPS_ENAB parameter is set to yes in the /etc/login.defs file and the group has no other members14.
