Development Tools Console Foundations Users and Permissions File Ownership

Does the superuser have ultimate authority over file permission?

After I have changed the permissions of a file to read only and have changed the user ownership to another user. I try to change the permissions knowing that file is not mine and I fail. I tried again with the super user and I succeeds. I could change it even though the file does not belong to me. How is that possible?

Hi Jose, the short answer is yes they do. Superuser also known as root, administrator, etc., has the authority needed to complete all tasks in any operating system.

It's important to note that if you are referring to using the sudo command, it can be limited in a way that using the root account can not.
