My enable.sh script got an update that makes it more useful when managing a Minecraft server.
Now instead of doing ./enable.sh | grep [pattern] and then doing ./enable.sh [mod_filename], you can accomplish it all in one go with ./enable.sh -g [pattern] which will grep the disabled directory for all of the mods matching the pattern and then generate a menu from that where all you have to do is hit the corresponding number to enable that mod.
