In Linux, users are organized into groups. This allows you to grant permissions to groups of users instead of individual users. This makes it easier to manage user permissions and security. However, there may be times when you need to remove a user from a group. For example, if a user leaves your company or if their role changes.To remove a user from a group in Linux, you can use the usermod command. This command allows you to modify user information, including their group membership.
