No need for the first uniq: sort, count, then sort by count. |

I think your first uniq will lose some data, since If not, I think skipping that would be an improvement. |

If you switch the columns and tab-separate them, they import into google docs for charting much more easily :)

Thanks, Ben. I was doing a bit to make it comma delimited, trying to learn a bit more awk. Here's what I added: |

Next up is to iterate over date ranges, so I can draw graphs over time of our codebase |

I approve. But, I'm not convinced of the utility of graphs over time. I've generated many of them over the years and can't remember making a change informed by them. I think they're driven by my insecurity about my work. However, I am convinced of the utility of insight into summarized repository state. I'd use this as a utility to ask "where do I need to focus my thinking?", not "where did I fail to focus in the past?" If you scriptify it, I recommend passing $* to the initial |

Gary, I think the graphs over time would be more of an interest from an archeological perspective, rather than changing my current habits. Thanks for the tip on passing $* to it. I'll do that when I build a script. Or, I could just make a function to put in my bash_profile, no? Maybe I'll ping you to help me. |

Yeah, it'd be fine as a function. A script makes it slightly more reusable for others since they just drop the file any where on their $PATH. |

True about making it more reusable. I could put it into my dotfiles repo. |

Or, you could, and I can just copy it. HAHA! |

Done. https://github.com/garybernhardt/dotfiles/blob/master/bin/git-churn I removed your grep for 'app|lib'. You can just pass directories straight to |

This might need some more work, haven't done anything with it for awhile, but this tracks files, classes, and methods for a ruby project |

I just found https://github.com/AnAppAMonth/git-churn, which is a python solution giving a more detailed interpretation of churn (additions, subtractions). |

I pipe this into a file, then I can load it into a spreadsheet.
Help me make it better!
