How to Add User to Sudoers list

How to add user to sudoers list, file, or group so that you can give a new user root access or privilege. Believe it or not, this is a fairly common question and in all reality the answer is quite simple. Adding a user to the sudoers file on a fully installed Linux system such as Ubuntu or Debian is possible via the visudo command. Users in the sudoers group are allowed privileges to run commands and open files as root or administrator. The following segment covers the simple process of adding a new root user to Ubuntu.

That’s really all there is to granting root access to a new user or to add user to sudoers list. You can repeat this process for as many users as you would like to add. Visudo might also come in handy for those times when you need to remove existing root users from the sudoers file.
