Usage: vault namespace delete [options] PATH

  Delete an existing namespace. The namespace deleted will be relative to the
  namespace provided in either the VAULT_NAMESPACE environment variable or
  -namespace CLI flag.

  Delete a namespace (e.g. ns1/):

      $ vault namespace delete ns1

  Delete a namespace namespace from a parent namespace (e.g. ns1/ns2/):

      $ vault namespace delete -namespace=ns1 ns2
