Very useful. Thanks!

It worked! I've starred this.

Thanks for this. It's worked fine for me.

A couple of comments:

1. At line 35, we do a which jekyll, but jekyll hasn't been installed yet.

2. What exactly does rehash do? I know what it does in bash.

3. Some of the docs were confusing, so I made updated version and put it in a gist. Consider it a pull request of a gist. https://gist.github.com/petdance/a121efa4e1ca8d1a8c371c91b9529574

Thanks again. Nice to have it all in one place.

Thanks!
