# Reclaims permissions back to the invoking user (from rootless docker 100000+ UID operating users)
# You can also: sudo chown ${USER}:${USER} -R .
# Great for git commits and backups.
# This script can be removed one day if rootless docker handles it, or if we switch to podman (slower than docker as of this writing).
