grep for stuff in multiple git repositories
===

So I've inherited a fairly large code base from some other developers, with code stored in various git repositories.

Sometimes, it's hard to know which project a particular piece of code might lie in, or if that piece of code even exists in git.

What I want to be able to do is grep ALL the projects for some particular piece of text.

I'm using gitosis, so all the git repositories are stored in /home/git/repositories with a structure like:

    /home/git/repositories
      |- project1
        |- HEAD
        |- branches
        |- config
        |- description
        |- hooks
        |- info
        |- objects
        |- refs
      |- project2
        |- ...

I've tried doing a recursive grep for stuff in the objects directories like this:

    grep -Hr "text" /home/git/repositories/*/objects

This fails to work as I intend of course, because the objects are stored in git's custom format.

What do?
