As I said before, I don't think auto-deleting corrupted refs is great in general, just because it can make a bad situation worse. But if you want the foot-gun, here's a more complete script that you could run. It _just_ looks in refs/remotes/, which is perhaps a bit safer. git for-each-ref --format='%(refname)' refs/remotes/ | git cat-file --batch-check='%(objectname)' | perl -alne 'print "delete $F[0]" if $F[1] eq "missing"' | tee /dev/stderr | git update-ref --stdin -Peff
