def get_pgid(path, follow_symlinks=True):
    '''
    Return the id of the primary group that owns a given file (Windows only)

    This function will return the rarely used primary group of a file. This
    generally has no bearing on permissions unless intentionally configured
    and is most commonly used to provide Unix compatibility (e.g. Services
    For Unix, NFS services).

    Ensure you know what you are doing before using this function.

    Args:
        path (str): The path to the file or directory

        follow_symlinks (bool):
            If the object specified by ``path`` is a symlink, get attributes of
            the linked file instead of the symlink itself. Default is True

    Returns:
        str: The gid of the primary group

    CLI Example:

    .. code-block:: bash

        salt '*' file.get_pgid c:\\temp\\test.txt
    '''
    if not os.path.exists(path):

    # Under Windows, if the path is a symlink, the user that owns the symlink is
    # returned, not the user that owns the file/directory the symlink is
    # pointing to. This behavior is *different* to *nix, therefore the symlink
    # is first resolved manually if necessary. Remember symlinks are only
    # supported on Windows Vista or later.
