So when I do sudo -s in my terminal I get into root mode, and after I do whatever I wanted to do, I do 'exit'. Now If I do 'sudo -s' again, the terminal does not ask for any password and enters root mode directly. Is this a normal behavior? I use ubuntu 16.04.
as I remember this was not the case 3-4 days ago,I think something has changed today,cant figure out what.
If this is not normal, how do i rectify it.
