Sometimes you just don't want git to keep absolutely everything that has ever been committed to a repo. Maybe you need to trim down your repo size to put it on github or push it to heroku, or maybe you are just a little OCD. Either way, here's hoping some of the scripts in here can help you.
These scripts have only been tested on Mac OS X. All help very very welcome :D
Shows the largest objects in the git repo of the current directory
find_fattest_objects.sh [-n <number_of_objects>] [-d] [-f] OPTIONS -n Show the n largest files in the repo (default 10) -d Filter out files that are currently in the project -f Show file paths only (useful for piping into other scripts)
Purge all history of the given objects from the repo
purge_objects.sh <file>... OPTIONS file One or more file paths to purge
To delete the 50 largest objects in your repo that are files that are not in your project anymore
find_fattest_objects.sh -n50 -d -f | xargs purge_objects.sh
