Remove refs/original/heads/master from git repo after filter-branch –tree-filter?

by

refs/original/* is there as a backup, in case you mess up your filter-branch. Believe me, it’s a really good idea.

Once you’ve inspected the results, and you’re very confident that you have what you want, you can remove the backed up ref:

git update-ref -d refs/original/refs/heads/master

or if you did this to many refs, and you want to wipe it all out:

git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d

(That’s taken directly from the filter-branch manpage.)

This doesn’t apply to you, but to others who may find this: If you do a filter-branch which removes content taking up significant disk space, you might also want to run git reflog expire --expire=now --all and git gc --prune=now to expire your reflogs and delete the now-unused objects. (Warning: completely, totally irreversible. Be very sure before you do it.)
