Usage: vault delete [options] path

  Delete data (secrets or configuration) from Vault.

  Delete sends a delete operation request to the given path. The
  behavior of the delete is determined by the backend at the given
  path. For example, deleting "aws/policy/ops" will delete the "ops"
  policy for the AWS backend. Use "vault help" for more details on
  whether delete is supported for a path and what the behavior is.

General Options:
