I've seen a few examples of adminmenu_custom floating around on this board. However, I couldn't find anything for admins that just want to download a file and have a good selection of commands to choose from. I took the script I use on my server, and modified it so server admins can just upload it to their server and be good to go. This will save admins time from learning how to code their own script and writing it. You can download it below:
