This will display untagged images, that are the leaves of the images tree (not intermediary layers). These images occur when a new build of an image takes the repo:tag away from the IMAGE ID, leaving it untagged. A warning will be issued if trying to remove an image when a container is presently using it. By having this flag it allows for batch cleanup.

Ready for use by?docker rmi ..., like:$ sudo docker rmi $(sudo docker images -f "dangling=true" -q)
