How to change sudo to not ask for your personal password

Filed under: user tipstricks — Antonio Portuesi @ 4:13 pm

On any default Ubuntu box, any task which requires root (or Administrator) privileges runs a program called sudo (or the graphical version, gksu) to run a helper program in a privileged mode.
By default, for security reasons, this program will ask you to input your personal password. When you make many settings changes on your system (or need to run applications as root), each password prompt can get rather annoying.
This tip will show you how to configure sudo to allow a specific user to run commands as root (or any other user you define) without prompting for a password.

The sudo program saves its configuration information in the text file /etc/sudoers. So you should edit this file:

user@pc:~$ sudo nano /etc/sudoers

and add the following line:


Replace #USER# with the username of the user you wish to add. E.g. if the username was bill, insert a string like that:


Now you will not have to give Ubuntu the password when you use sudo.
