          Under X11 you could use xprop to listen for all window activation events and then execute some logic that depends on window class name.



          #!/bin/bash

          xprop -spy -root _NET_ACTIVE_WINDOW | grep --line-buffered -o '0[xX][a-zA-Z0-9]7' |
          while read -r id; do
          class="$(xprop -id $id WM_CLASS)"
          if [ -n "$class" ]; then
          echo "Active window class is: $class"
          fi
          done
