Sudoers

Use sudo without being asked for your password

Run in a terminal:

sudo visudo

The sudoers file will be opened with your default editor. There add this line at the end of the file:

username ALL=(ALL) NOPASSWD: ALL

Then save and exit.

Change root’s password when sudoers file is misconfigured and sudo won’t work

If you misconfigure the sudoers file you may end up in a situation where you wouldn’t be able to use sudo. This could be easely fixed by just using su to became root and then fixing the sudoers…
