Adjust WM_CLASS of Android Studio Beta version on GNU/Linux (and X.org) so you can have 2 different icons on docks

fix-wm-class-on-linux.sh

#!/bin/sh
# Update WM_CLASS

fault_tolerance=0
beta_timeout=50
while true; do
    wids=$(timeout 2 xdotool search --sync --onlyvisible --class "jetbrains-studio")
    if [ -z "$wids" ] ; then
        if [ $fault_tolerance -eq 0 ]; then
            fault_tolerance=1
        else
            echo "Can't find any Android Studio Beta window"
            exit 0
        fi
    else
        fault_tolerance=0
    fi
    for wid in $wids; do
        pid=$(xdotool getwindowpid $wid)
        if [ ! -z "$pid" ] ; then
            path=$(readlink -f /proc/$pid/exe)
            if [[ $path == *"beta"* ]]; then
                echo "Find Android Studio Beta window!"
                beta_timeout=50
                xprop -id $wid -f WM_CLASS 8s -set WM_CLASS "jetbrains-studio-beta"
            else
                beta_timeout="$(($beta_timeout-1))"
                if [ $beta_timeout -eq 0 ]; then
                    echo "Can't find any Android Studio Beta window"
                    exit 0
                fi
            fi
        fi
    done
done
