Stay ahead of git with this sharp script

I work on quite a few git repositories at once, and I don’t always commit changes in one before making changes to another. Or if I do, I don’t always push the changes up straight away. That might not be best practice in software development, but hey, it’s what I do. The issue for me is remembering what state each repo is in. Here’s the script I use to tell me.

How to use zmv — Z Shell’s super-smart file renamer

I’d like to introduce you — if you’re not already acquainted — to the Z Shell’s incredibly handy function zmv.
