Case-insensitivity with OS X using git

Today, I got bitten by OS X being case-insensitive while using git. I had a directory models with JavaScript files in it named account.js, project.js, and event.js. I decided that the models should be capitalized. Sure, no problem using trusty mv.

When I looked in git though, no changed files. WTF? I even tried changing another file and committing. Looking in the web GitHub file browser, the files were still all lowercase.

Turns out the solution is to use git mv -f.

➜  models git:(master) git mv -f account.js Account.js
➜  models git:(master) ✗ git mv -f project.js Project.js
➜  models git:(master) ✗ git mv -f event.js Event.js
➜  models git:(master) ✗ git status
    On branch master
    Changes to be committed:
      (use "git reset HEAD <file>..." to unstage)

          renamed:    account.js -> Account.js
          renamed:    project.js -> Project.js              
          renamed:    event.js -> Event.js
