      subprocess.check_call(command, shell=isinstance(command, string_types), bufsize=-1)
docs: A convenience wrapper around subprocess.check_call that logs the command before passing it
      on. The command can be either a string or a sequence of strings. If it is a string shell=True
      will be passed to subprocess.check_call.
