I'm using an Arch Linux system for a small private Minecraft Server. I'm using custom MC Server software called Bukkit. I'm using the development builds, so there are frequent updates. Which means every time there's an update, I have to delete the old jar and download the new one. I decided to try to make a simple script that would automatically delete the old one and download the newer version. The problem is, I don't know how to make wget (or curl) check to see if there is a new version of the jar. The name of the jar itself doesn't change, but the directory it's under does. The builds are at http://dl.bukkit.org/downloads/craftbukkit. Can anyone help me with this? Thanks!
