Understanding User Roles Concepts
In Windows or MacOS, when you create a file or folder, you can set permissions only for yourself or for all users on your computer. In Linux, there's a bit more control. When you create a file or folder, you can set permissions for three groups of people:
-
Owner: that's you, the one who created the file or folder. You can decide what can and cannot be done with this file or folder, like who can read, write, or delete it;
-
Group: you can also create a special group of people who have access to this file or folder. These could be your friends or colleagues. You can set permissions for this group separately from the ones you set for yourself;
-
Others: these are all the other people who use this computer but aren't the owners or part of the group. You can also set permissions for them, determining what they can or cannot do with your file or folder.
This allows you to control who has access to your file or folder and what actions they can perform. It's an important security aspect in Linux that helps protect your data from unwanted changes.
Up to this point, youβve been performing all actions as root user. The root user in Linux has the highest access rights and full control over the system. They can perform any system-level operations. Youβll learn how to create and manage new users, user groups, and their access rights.
