Graphical Linux command: Deleting a group with the Groupdel command

When we create many different groups, it is likely that they will not be needed for different reasons. When a pair of computers is no longer needed by us, our usual practice is to delete it. This frees up all the resources that are available to the computer because the computer's resources are limited.

In the Linux system, I use the Groupdel command to delete the user group. The command format for deleting a group is very simple, and you can enter the name of the group after the Groupdel command. Please try typing the command in the terminal: Groupdel hello. Hello is a group name in my Linux system, and friends learn to replace it with the group name in their system.

In this way, a group called Hello in my Linux system does not exist. What if we entered an Groupdel group name after the command?

Saharan！ The system gives a hint: "Groupdel:group Helloo does not exist" means "group Helloo does not exist". Then we are not likely to encounter another problem, when we delete a group, there are users in this group. What will the terminal system do?

Obviously, the "Hello" group cannot be deleted.
