// Cobra supports Persistent Flags which will work for this command
// and all subcommands, e.g.:
// showCmd.PersistentFlags().String("foo", "", "A help for foo")
// Cobra supports local flags which will only run when this command
// is called directly, e.g.:
// showCmd.Flags().BoolP("toggle", "t", false, "Help message for toggle")
