Can you replace missing characters in the script parameters?


I'd like to set up a script that would launch an app (lets call it "Annoyance" ) and set WM_CLASS for it using xprop command.So it would be something like:

#!/bin/bash
/pathtoannoyance & sleep 10s && xprop -name "window_name" -f WM_CLASS -set WM_CLASS "Annoyance"

The problem is that "window_name" varies, depending what file I open with Annoyance. So when I open file1 the title is "file1-Annoyance", when I open file2 it is "file2-Annoyance" and so on.

Thus I wonder whether it is possible to make xprop look only for the last letters in the window title?

But on the other hand that might cause other problems - if I open a couple of windows and if only the last letters will be used xprop won't know which windows needs to get a WM_CLASS assigned (thinking out loud...).

Any ideas on the solution?

You could pass the window name as a variable instead and modify it before using such that the unwanted characters are removed.

PS. Wrapping your source code in [code] [/code] tags will make it more readable.
