Publish a command from the minion out to other minions.

    Publications need to be enabled on the Salt master and the minion
    needs to have permission to publish the command. The Salt master
    will also prevent a recursive publication loop, this means that a
    minion cannot command another minion to command another minion as
    that would create an infinite command loop.

    The ``tgt_type`` argument is used to pass a target other than a glob into
    the execution, the available options are:

    - glob
    - pcre
    - grain
    - grain_pcre
    - pillar
    - pillar_pcre
    - ipcidr
    - range
    - compound

    .. versionchanged:: 2017.7.0
        The ``expr_form`` argument has been renamed to ``tgt_type``, earlier
        releases must use ``expr_form``.

    Note that for pillar matches must be exact, both in the pillar matcher
    and the compound matcher. No globbing is supported.

    The arguments sent to the minion publish function are separated with
    commas. This means that for a minion executing a command with multiple
    args it will look like this:

    .. code-block:: bash

        salt system.example.com publish.publish '*' user.add 'foo,1020,1020'
        salt system.example.com publish.publish 'os:Fedora' network.interfaces '' grain

    CLI Example:

    .. code-block:: bash

        salt system.example.com publish.publish '*' cmd.run 'ls -la /tmp'


    .. admonition:: Attention

        If you need to pass a value to a function argument and that value
        contains an equal sign, you **must** include the argument name.
        For example:

        .. code-block:: bash

            salt '*' publish.publish test.kwarg arg='cheese=spam'

        Multiple keyword arguments should be passed as a list.

        .. code-block:: bash

            salt '*' publish.publish test.kwarg arg="['cheese=spam','spam=cheese']"


    When running via salt-call, the `via_master` flag may be set to specific which
    master the publication should be sent to. Only one master may be specified. If
    unset, the publication will be sent only to the first master in minion configuration.

def publish(tgt,
            fun,
            arg=None,
            tgt_type='glob',
            returner='',
            timeout=5,
            via_master=None):
