        Compound commands can be used for multiple executions in a single
        publish. Function names and function arguments are provided in separate

        used if no arguments are required.

        :param tgt: Which minions to target for the execution. Default is shell
            glob. Modified by the ``tgt_type`` option.
        :type tgt: string or list

        :param fun: The module and function to call on the specified minions of
            the form ``module.function``. For example ``test.ping`` or
            ``grains.items``.

            Compound commands
                Multiple functions may be called in a single publish by
                passing a list of commands. This can dramatically lower
                overhead and speed up the application communicating with Salt.

                This requires that the ``arg`` param is a list of lists. The
                ``fun`` list and the ``arg`` list must correlate by index
                meaning a function that does not take arguments must still have
                a corresponding empty list at the expected index.
        :type fun: string or list of strings

        :param arg: A list of arguments to pass to the remote function. If the
            function takes no arguments ``arg`` may be omitted except when
            executing a compound command.
        :type arg: list or list-of-lists

        :param timeout: Seconds to wait after the last minion returns but
            before all minions return.

        :param tgt_type: The type of ``tgt``. Allowed values:

            * ``glob`` - Bash glob completion - Default
            * ``pcre`` - Perl style regular expression
            * ``list`` - Python list of hosts
            * ``grain`` - Match based on a grain comparison
            * ``grain_pcre`` - Grain comparison with a regex
            * ``pillar`` - Pillar data comparison
            * ``pillar_pcre`` - Pillar data comparison with a regex
            * ``nodegroup`` - Match on nodegroup
            * ``range`` - Use a Range server for matching
            * ``compound`` - Pass a compound match string
            * ``ipcidr`` - Match based on Subnet (CIDR notation) or IPv4 address.

            .. versionchanged:: 2017.7.0
                Renamed from ``expr_form`` to ``tgt_type``

        :param ret: The returner to use. The value passed can be single
            returner, or a comma delimited list of returners to call in order
            on the minions

        :param kwarg: A dictionary with keyword arguments for the function.

        :param full_return: Output the job return only (default) or the full
            return including exit code and other job metadata.

        :param kwargs: Optional keyword arguments.
            Authentication credentials may be passed when using
            :conf_master:`external_auth`.

            For example: ``local.cmd('*', 'test.ping', username='saltdev',
            password='saltdev', eauth='pam')``.

            token='5871821ea51754fdcea8153c1c745433')``

        :returns: A dictionary with the result of the execution, keyed by
            minion ID. A compound command will return a sub-dictionary keyed by
            function name.
