Hi Gabriel, nice tutorial, enjoyed it. Can you clarify and state best practices, please. I have 2 directories, ACCOUNTS, and OFFICE, both set to 2770 and ACCOUNTS is owned by group “department1″, and OFFICE is owned by group ” department 2″ both groups users can only use and see their own directories.

This all works fine but a new user “JOHN” wants to be able to access and modify BOTH directories, can you tell me how to make this happen, whats best practice?

In reply to kiran. @Kiran, To delete multiple users at a time in Linux, use the following command.

# for u in user1 user2 user3 user4; do echo "$u"; userdel -r "$u"; done

Alternatively, use the following command to delete multiple system users in Linux.

# for user in `cat del.user`;do userdel $user;done

explanation of the above command.

user - It is the variable used to store values from del.user file.
del.user - It is the file with all user names that you want to delete.
userdel - A command used to delete the user.
userdel -r - This command used to delete user's with home directory.

Nice article appreciate your work. But make one correction here for unlocking a user you have to use "usermod -U username" instead of using small "u", use capital U. Because with small u we can assign new UID for the user. its not for Unlocking a user.

Create a bash script to perform user management tasks like creating a new group. The script must check to ensure that no duplicate group names exist on the system. If a duplicate is found, an error needs to be reported, and the administrator must try another group name.
