def show_pillar(minion="*", **kwargs):
    """
    Returns the compiled pillar either of a specific minion
    or just the global available pillars. This function assumes
    that no minion has the id ``*``.
    Function also accepts pillarenv as attribute in order to limit to a specific pillar branch of git

    CLI Example:

    shows minion specific pillar:

    .. code-block:: bash

        salt-run pillar.show_pillar 'www.example.com'

    shows global pillar:

    .. code-block:: bash

        salt-run pillar.show_pillar

    shows global pillar for 'dev' pillar environment:
    (note that not specifying pillarenv will merge all pillar environments
    using the master config option pillar_source_merging_strategy.)

    .. code-block:: bash

        salt-run pillar.show_pillar 'pillarenv=dev'

    shows global pillar for 'dev' pillar environment and specific pillarenv = dev:

    .. code-block:: bash

        salt-run pillar.show_pillar 'saltenv=dev' 'pillarenv=dev'

    API Example:

    .. code-block:: python

        import salt.config
        import salt.runner
        opts = salt.config.master_config('/etc/salt/master')
