• x11-wait-for-topmost.sh
• x11-xprop-get-topmost.sh (x11-wait-for-topmost.sh depends on this file)

• WM_CLASS is the class name of the window you are targeting e.g. osso-xterm, camera-ui;
• (optional) EVENT is the type of event you are looking for: focus or blur - focus simply means that the window has become top-most, and blur meaning that the targeted window is no longer top-most (defaults to focus);
• (optional) TIMEOUT is the number of seconds before exiting if the focus/blur event on the target windows has not occurred (defaults to 600 seconds i.e. 10 minutes)

./x11-wait-for-topmost.sh camera-ui
./x11-wait-for-topmost.sh camera-ui focus

Both of these commands do the same thing, the script will wait until the camera application runs and receives the focus (try opening the camera slide).

• The script will print the text event-triggered to stdout when it is successful. You can easily use another script to capture and test for this output.
• x11-xprop-get-topmost.sh is the file that actually calls xprop. If you want to see the bare-bones xprop calls, you will find it inside this file.
• Both files are designed to be reusable in your own scripts. They also come with some sanity checks built-in e.g. x11-xprop-get-topmost.sh actually checks first if you have xprop installed.
• You do not have to be root to run either script.
