# A script to delete namespace(s) stuck at "Terminating" state, that won't get deleted, within the OpenShift cluster. 
# You'll see an error message like this below, when you try "oc delete project <namespace>"
#
# Error from server (Conflict): Operation cannot be fulfilled on namespaces "<namespace>": The system is ensuring all content is removed from this namespace. Upon completion, this namespace will automatically be purged by the system.
