Ubuntu: Can I display volume or brightness popup using command?


When you adjust your brightness or volume in ubuntu, you would see a popup notification in the top right corner of the screen to notify you the level of brightness or volume. Just as follows:

volume popup

I can adjust the volume with the command amixer -D pulse sset Master 10%+, but I don't know the volume level after executing the command each time. So I thought maybe I could add a command to display the volume popup. Is there a command that is able to do the trick?
