What purpose does this server when bypassing is as easy as typing sudo?

Forgive the naivety here but I am a rookie and I'm sure there has to be a good reason for this, and I'd like to know that.

  • Thanks @izx. Did not notice that before. I actually didn't even know su exists till now. New to Ubuntu. – Programming Noob May 31 '12 at 15:25
  • If you are already admin (which everyone is on default Ubuntu install), then all `sudo` does is make sure you think before you do something that may be potentially dangerous if done wrong (typo, etc.) – ish May 31 '12 at 15:27

Security! ;-)

Only admin users can do sudo and even those have to provide a password, i.e. if you leave your screen for a minute, nobody can do sudo without the password.
