	defer client.Close()

	sb, err := client.Create(ctx, cubesandbox.CreateOptions{})
	if err != nil {
		panic(err)
	}
	defer sb.Kill(ctx)
	info, err := sb.GetInfo(ctx)
	if err == nil {
		fmt.Printf("info %v", info)
	}
	exec, err := sb.RunCode(ctx, "x = 41\nx + 1", cubesandbox.RunCodeOptions{})
	if err != nil {
		panic(err)
	}
	fmt.Printf("exec %+v \n",exec)
	fmt.Println("test command end")

	result, err := sb.Commands().Run(ctx, "sleep 10000", cubesandbox.CommandOptions{})
	if err != nil {
		panic(err)
	}
	fmt.Println(result)
}
