Keep in mind that you must use the sudo command to see or change the sudoers file. These users must have an entry in the "/etc/sudoers" file to be able to use the sudo command. We can have several administrators thanks to sudo. The sudo command Linuxnux, often known as "superuser do," enables a user with the necessary permissions to run a command in the role of another user on Unix-like operating systems. This option is similar to Windows run as an administrator option`. Any command that has the "sudo" prefix will run with elevated privileges, or in other words, allow a user with the necessary rights to execute a command in the role of another user, such as the superuser.
