Download the most recent minecraft version (snapshot)

mostRecent.sh

#!/bin/bash

# Download version file
wget -qN https://launchermeta.mojang.com/mc/game/version_manifest.json

# Beautify the file
python -m json.tool version_manifest.json > versions.json

# Get the latest snapshot release
MCVER=`sed -n -e '/\"latest\"/,/}/ s/.*\"snapshot\": \"\([^\"]*\)\".*/\1/p' < versions.json`

# Download the latest snapshot release
wget -N https://s3.amazonaws.com/Minecraft.Download/versions/$MCVER/minecraft_server.$MCVER.jar

# Delete temp files
rm versions.json
rm version_manifest.json

This actually helped me because I need the links to make my customized launchers
