Script to replace URL in clipboard with a shorter one using zws.im, probably assign a keyboard shortcut to run this script.

shorten-clipboard.sh

original=`xclip -o -sel clipboard`

if [[ $original == https://zws.im* ]]; then
  notify-send "Already shortened" --icon=gtk-edit
  exit 1;
fi

json=$(curl -s "https://us-central1-zero-width-shortener.cloudfunctions.net/shortenURL?url=$original")

if [ $? -eq 0 ]; then
    short="https://zws.im/$(echo $json | jq -jr '.short')"

    if [ $? -eq 0 ]; then
        printf $short | xclip -sel clip
        notify-send "Link shortened" --icon=stock_cut
    else
        notify-send "Shortening failed" --icon=gtk-quit
    fi
else
    notify-send "Shortening failed" --icon=gtk-quit
