Does this answer your question? [Is there a linux command to determine the window IDs associated with a given process ID?](https://stackoverflow.com/questions/2250757/is-there-a-linux-command-to-determine-the-window-ids-associated-with-a-given-pro) – tdy Sep 18 '21 at 08:26

2What information do you want about the window, and what will you do with it? – tgdavies Sep 18 '21 at 08:46

@tgdavies, The WID of the window will be great. – Alfred.37 Sep 18 '21 at 09:09

Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. – Community Sep 25 '21 at 05:01

I cannot test this at the moment, but maybe xdotool offers a way to get the window under the mouse cursor. From man xdotool:
getmouselocation [--shell]
Outputs the x, y, screen, and window id of the mouse cursor.
I assume the mentioned window id belongs to the window under the mouse cursor. To retrieve it, use
declare "$(xdotool getmouselocation --shell | grep WINDOW)"
echo "$WINDOW"
The window id can then be used in other tools like xwininfo -id <wdid> to get more information.
