Hello,

I have the following script running when I press Mod4+Enter :

#!/bin/bash
i3-msg '[instance="nextURxvt"] move workspace current'
WINDOW_ID=`xwininfo -tree -root|grep nextURxvt|awk '{print $1;}'`
xprop -id $WINDOW_ID -f WM_CLASS 8ss -set WM_CLASS "urxvt"
i3-msg 'exec urxvtc -name nextURxvt'

What it does is :

• Pull the URxvt instance named nextURxvt from the scratchpad to the current workspace.
• Change its WM_CLASS from WM_CLASS(STRING) = "nextURxvt", "URxvt" to WM_CLASS(STRING) = "urxvt"
• Open a new urxvt in the scratchpad (the mapping is in my i3 config).

The problem is : when I do i3-msg '[instance="nextURxvt"] move workspace current', even the renamed URxvt's are moved to the current workspace, even though if I run xprop|grep nextURxvt there is nothing.

What is wrong ? Thanks
