On someone's ubuntu VPS I created a user, added them to sudo and logged in.
Figuring I didn't need the root password anymore, I got rid of it. Then for whatever reason I felt I needed to go back to root.
I type in
sudo -s and put in the users password. Then before my command it said something like
Then I could su root.
Just wondering what bash is, how I could switch to it before and I can't on my current vps.
