sgr prune [OPTIONS] REPOSITORY
Cleanup dangling images from a repository.
This includes images not pointed to by any tags (or checked out) and those that aren't required by any of such images.
Will ask for confirmation of the deletion, unless
-yis passed. If
passed, this will perform deletion on a remote Splitgraph engine (registered in the config) instead, assuming
the user has write access to the remote repository.
This does not delete any physical objects that the deleted repository/images depend on:
sgr cleanup to do that.
-r, --remote : Perform operation on a different remote engine
-y, --yes: Agree to deletion without confirmation
