Stop terminal from asking for a sudo password.

You have to edit the sudoers file, for which there will be an entry for you.

sudo nano /etc/sudoers  

To allow all users of the group admin to use the sudo command without a password, add the following:

%admin ALL=(ALL) NOPASSWD: ALL

If you want to restrict it to a single user such as Jak, use this instead of %admin.

You can then save the file, and it will take affect immediately.
