What is adding groups in Linux?

In Linux, adding groups is an essential task for managing user permissions and system access. Groups allow you to organize users who share similar access needs, making it easier to manage permissions collectively rather than individually. By creating groups, you can assign specific rights and roles to multiple users at once, simplifying administration and enhancing security.

To add a group in Linux, you can use the command `groupadd` followed by the group name. Here’s a simple example:

This command creates a new group named "developers". Once the group is created, you can add users to this group using the `usermod` command.
