See current file size. First need to git gc
Alistair@MONET ~/Documents/Research/Projects/Chromatin/Code (master)
$ git gc
Counting objects: 713, done.
Delta compression using up to 8 threads.
Compressing objects: 100% (570/570), done.
Writing objects: 100% (713/713), done.
Total 713 (delta 257), reused 459 (delta 142)
Now we can count objects. size-pack is the size of our database in Kb (70+ Mb here!)
Alistair@MONET ~/Documents/Research/Projects/Chromatin/Code (master)
$ git count-objects -v
count: 7
size: 22
in-pack: 713
packs: 1
size-pack: 70827
prune-packable: 0
garbage: 0
Here we get rid of the offending file. For more details on all of this, including a good guide on how to find the offending big file(s), see this part of the Git Pro Book.

Ref 'refs/heads/master' was rewritten
Now some cleanup. We remove the refs and logs
Alistair@MONET ~/Documents/Research/Projects/Chromatin/Code (master)
$ rm -Rf .git/refs/original
Alistair@MONET ~/Documents/Research/Projects/Chromatin/Code (master)
$ rm -Rf .git/logs/
And we want to remove the rewrite backup so that everything is back to normal. Otherwise if we need to do this again we will get errors objecting to our editing the rewrite folder. I haven’t found as good references to support this move so maybe do with caution.
Alistair@MONET ~/Documents/Research/Projects/Chromatin/Code (master)
$ rm -rf .git-rewrite/
Now let’s see how we’re doing on space
