Git-filter-orphans will find all your orphaned objects and eradicate them from your git history and repo completely.

find -find all orphan objects and store them in a list($SORT_FILE) update -update your new repo and force push to remote clone -make a backup of your current repo and clone from it in: $REPO_ROOT gc -run manual garbage collection on repo (potentially dangerous) rebase -similar to checkout, but used to important rewrites already made to a remote repo so you don't need to reclone the entire repo again checkout -checkout all remote branches, !IMPORTANT - this must be done before you filter in order to filter all branches properly for push purge FILE -purge an object list, expects a gfo-sorted.txt type of list --tmp DIR -an off-disk temporary directory to optimize the filter process the directory will be created and deleted on completion rmdir PATH -recursively filter all items of a directory[PATH]; you can also pass in a text based file similar to gfo-sorted.txt and use it as a list of directories to delete --tmp DIR -same as above filter PATH -filter a single orphaned file or directory, will not recurse a directory --tmp DIR -same as above help GIT-USERNAME CLONE-REPO -this menu, you can pass a username and clone-repo name into the params be used in place of and below Note: might be a good idea to test this on a cloned version of your repo

cd && git clone https://github.com/sparkida/git-filter-orphans
cd /usr/bin && sudo ln -s ~/git-filter-orphans/git-filter-orphans gfo

• build list file -> gfo-sorted.txt $ $REPO> gfo find

• confirm contents of the generated list $ $REPO> cat gfo-sorted.txt

• purge the list created in "gfo-sorted.txt": $ $REPO> gfo purge gfo-sorted.txt

This assumes you want to create a clone of your repo for liability purposes and have already created a new repo for this.

#create the clone $ > git clone --bare [email protected]:$GIT_USER/$REPO ${REPO}.git $ > cd ${REPO}.git $ ${REPO}.git> git push --mirror [email protected]:$GIT_USER/$CLONE_REPO

#clone the new remote repo $ ${REPO}.git> cd .. && git clone [email protected]:$GIT_USER/$CLONE_REPO && cd "$CLONE_REPO"

#checkout all the branches, or you can manually checkout branches, just be sure to check back in to master $ $CLONE_REPO> gfo checkout

#create a $SORT_FILE file of orphaned objects and their size in bytes $ $CLONE_REPO> gfo find

#the $SORT_FILE looks good #lets delete the items in it with git-filter-branch $ $CLONE_REPO> gfo purge $SORT_FILE

#now we have a clean repo ready to be pushed, this runs gc $ $CLONE_REPO> gfo update

#!important anyone else using this repo will need to fetch all the updated refs #but you will not have to do this $ $CLONE_REPO> gfo rebase
