I want to have some statistics about my project and what the team has done over the past years. I know there's git log --stat <file name> which gives you a log with all the modifications that were made on that specific file. Is there a way to run this git log --stat on every file of my project and output to a file?
Thank you.
There is not a native way to do this in git, however there are two projects that add this functionality by parsing git commands of may git commands. Both are called git fame one is implemented in ruby and one is implemented in python. While the are called the same thing, they have slightly different feature sets.
Instead of parsing git log, however the both parse the results of git blame in porcelain mode iterating over all the files tracked via git ls-files.
Git Fame Python sample output:
