How can I get coloured patches with git interactive on bash?

Question

I am using git add -i to select patch hunks to add or not.

I've learned using git by watching videos at http://gitcast.com. On their videos, I see that the patch output when using git add --interactive are coloured (on OSX?). When I do the same on my system (Linux/Kubuntu/bash), the patches are not colored (the usual shell colours, i.e. white/black).

How can I have a coloured output?

Answer 1

In .gitconfig

[color]
  status = auto
  diff = auto

Your terminal will need to support colour, of course. There's more info here.
