Get Windows like App Hotkey Start-up behavior. First Argument: Path to app. Second argument: App-class (wmctrl -lx)

hotkey.sh

#!/bin/bash


contains() {
    [[ $1 =~ $2 ]] && return 0 || return 1
}


app_list=$(wmctrl -lx | awk '{print $3}')
if contains "$app_list" "$2";
	then wmctrl -x -a "$2" ;
	else ("$1"&) ;
fi
