Question

Each line of the file should be examined and the following errors detected if they exist:1)If the UID is greater than 500 then make sure the specified shell is listed in the /etc/shells file and the permissions of the home directory are 700.2)If the UID is 0 then make the username is root and the GID is 0.Make sure there are no duplicate UID
