Passwordless Sudo

If you're the only one who uses your computer, you trust yourself, your password is long and you don't have the patience to type it every time you use sudo, here's a tip. With the visudo command you edit the /etc/sudoers file to change sudo's settings.

$ sudo visudo

At the end of the file, insert the following line, replacing leonardo with your username:

leonardo ALL=(ALL) NOPASSWD: ALL

Save the file and you're done. Passwordless sudo!
