Gregory's Server@b0rk i dont believe "git diff" will do a side by side compare, but i use `git diff --word-diff=color` pretty often, so that it highlights word changes instead of whole lines.
if you add `--no-index` you can diff two files against each other regardless of whether they are in a git repo or not.
@vfig @b0rk I do this too, mostly because it already exists on many questions these days, so I don't have to install anything or have internet access. I also sometimes use --word-diff-regex to change the concept of a word (e.g. if I want to look for single character changes).
