How can I use wmctrl to check if a certain WM_ICON_NAME(STRING) exists?

Question

I'm using I3 and I use WM_ICON_NAME(STRING) to identify my windows.

I'm looking for something similar to this, but with WM_ICON_NAME(STRING). It is possible to achieve this? Thank you.

if test $(wmctrl -l | grep "name of my window" 2>&1 | wc -l) -eq 1; then 
    echo "the window exists"
fi

There are not many tools that use WM_ICON_NAME as it is often assumed to be set to the same as WM_NAME. You can list all the window ids and run xprop on each of them to get a line such as

WM_ICON_NAME(STRING) = "myname"

and then use awk (or similar) to extract the quoted part of this and compare it to the wanted string. Here's a bash function findicon taking one parameter to do this:

findicon(){ 
    local myname=${1?}
    wmctrl -l |
    while read id rest
    do xprop -id "$id" WM_ICON_NAME
    done |
    awk -F'"' -v myname="$myname" '
        {if($2==myname)found=1} 
        END {exit !found}'
}

if findicon 'my icon name'
then echo 'found'
fi

You could use xdotool to search existing windows by their class names and titles.

if xdotool search --name "name of my window" > /dev/null; then
    echo "Window found"
else
    echo "Window not found"
fi

In above code example xdotool command will return exit status 0 and list of found window id's if there are some windows which title contains "name of my window".
