Removing groups

You can remove a group if it is no longer needed. To demonstrate, let's create a group named temp:

root@ubuntu-linux:~# groupadd temp

Now, you can use the groupdel command to remove the temp group:

root@ubuntu-linux:~# groupdel temp

Now, let's try removing the group sara:

root@ubuntu-linux:~# groupdel sara
groupdel: cannot remove the primary group of user 'sara'

We get an error message as we are not allowed to remove primary groups of existing users.
