How to set up a shortcut to open/track/minimise an app on Linux

For e.g. with yakuake, by default the shortcut is F12, you can open it or track it anywhere, just the same window. If it’s focused, press F12 again gonna minimize it.

My app here is eudic. Create such a sh file somewhere:



if [[ $(xprop -id $(xdotool getactivewindow) WM_CLASS) =~ \"$wm_class\" ]] {
  xdotool getactivewindow windowminimize
} else {
  wmctrl -xR $wm_class

pgrep -u $USER -x $process || exec $terminal &
