This is the targeted script mentioned above:

//Add your script here. Feel free to use the available api properties and methods
// If download link is present in history file, mark it as duplicae (add "#duplicatelink" to comment)
// Trigger required: Packagizer Hook

if (state == "AFTER") {
    var url = link.getURL();
    var historyFile = getPath(JD_HOME + "/cfg/history.txt");
    var history = historyFile.exists() ? readFile(historyFile) : "";

    if (history.indexOf(url) > -1) {
        var text = "#duplicatelink";
        var comment = link.getComment();
        comment = comment ? text + " " + comment : text;
        link.setComment(comment);
      //  link.enabled = false;
      sleep(1000)
      link.remove();
    }
}

This the even script export
