Passwordless sudo

When executing commands as another user, then sudo is your friend.

Of course, one needs to authenticate correctly. But in day-to-day work it is tedious having to provide the password all the time.

The sudo-command can be made “passwordless” by using a tool called visudo.

Just type

sudo visudo

and your favourite editor will open.

Add the following line at the very bottom (important!)

 username   ALL=(ALL) NOPASSWD:ALL

That allows the user with name to execute commands as root-user.
