Git LFS Sync between remotes

git-lfs-sync.sh

#!/bin/bash
# Sync two git LFS remotes. This is very useful when you
# have two remotes (e.g. upstream and fork) and they have
# different files on the LFS storage. Trying git lfs fetch --all
# yields an error for missing objects if the two repos are not 
# synced. The purpose of this script is to overcome this issue
# with Git LFS
#
# Usage: git-lfs-sync.sh source destination branch
