How to Add a User to a Group on a Linux Server

User groups play an important role in any Linux operating system and its distributions. Groups make it easier to manage larger amounts of users, giving you the ability to give all of them the same security and access privileges. For example, files and devices may be granted access based on a user’s ID or group ID. Groups allow you to set a file’s permission for the entire group instead of setting permissions for each individual user. Overall, this makes managing permissions for your server’s users a very simple and straightforward process. Let’s show you how to add users to groups on a Linux VPS.
