churn.sh

git log --name-only | grep xaml | sort | uniq -c | sort -Descending > xaml-files-by-tfs-commit-count.txt

What it does:
    - looks at the git log file, retrieving just the filenames;
    - greps to extract xaml filenames;
    - sorts the list of files to get the duplicates together;
    - eliminates the duplicates but keeps a count of them;
    - resorts the file names by that count; and
    - writes the list to a txt file named xaml-files-by-tfs-commit-count.txt

Note: This works in PowerShell.
