Minecraft server crontab

cron.sh

#!/bin/sh

# Set this to the directory where everything will be moved.
FINAL_DIR=/var/www/mc

# Requirements:
#  * pigmap, found here: https://github.com/equalpants/pigmap
#  * mcmap, found here: https://github.com/Zahl/mcmap
#  * rsync
#  * pngcrush
#
# After compiling pigmap, you'll want to run these commands to generate the first map *before*
# running this script. Replace $FINAL_DIR with the directory you set above. I suggest shutting
# down the server to copy the world folder. You may start the server back up when running pigmap.
#
#    cp -r ./world ./world-backup/world
#    ./pigmap -B 6 -T 1 -Z 10 -i ./world -o $FINAL_DIR/map -g ./pigmap-data -h 3
#
# The following are required by default, but can be removed from
# the script if you want. They are marked in the code with (OPTIONAL):
#  * Python with PIL
#  * Imagemagick
