You should try out fish[1], one of the features that makes it great is that it does exactly what the chrome omnibox does, just with commands. It shows what it will complete after you press ^F and it is a lot of times correct.

It also has lots of other features, like tab completion that tells you what the options of commands do. So reading the manpages or typing -h is generally not needed.

If you do try it, also try one of the themes of oh-my-fish[2], most of them have a git thing that lets you know if you have uncommitted stuff and on what branch you are.
