Keeping GeoIP database updated

Here’s a simple script to install on a server to keep the GeoIP db updated.
Source code for file (e.g.) get_latest_GeoIP.sh
#!/bin/bash
# getting the latest GeoLiteCity database from maxmind
host=$(hostname -s)
stamp=`date +"%m%Y"` # getting current month & year for GeoLiteCity filename
if [ -f "/usr/share/GeoIP/GeoLiteCity_"$stamp".dat" ]; then
last=`date -r /usr/share/GeoIP/GeoLiteCity_"$stamp".dat +"%m%Y"`
else
last=0000
fi
if [ ! -f "/usr/share/GeoIP/GeoLiteCity_"$stamp".dat" ] || [ "$stamp" != "$last" ]; then # if current file doesn't exist or current file wasn't modified in the current month
wget -O "/usr/share/GeoIP/GeoLiteCity.dat.gz" http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
if [ ! -s "/usr/share/GeoIP/GeoLiteCity.dat.gz" ]; then
rm /usr/share/GeoIP/GeoLiteCity.dat.gz
exit 1
else
rm /usr/share/GeoIP/GeoLiteCity.dat
gunzip /usr/share/GeoIP/GeoLiteCity.dat.gz
if [ -f "/usr/share/GeoIP/GeoLiteCity_"$stamp".dat" ]; then
rm /usr/share/GeoIP/GeoLiteCity_"$stamp".dat
fi
mv /usr/share/GeoIP/GeoLiteCity.dat "/usr/share/GeoIP/GeoLiteCity_"$stamp".dat"
ln -s "/usr/share/GeoIP/GeoLiteCity_"$stamp".dat" /usr/share/GeoIP/GeoLiteCity.dat
echo "Report: GeoIP Database "$stamp" has been updated on "$host". - Enjoy!"
fi
fi
exit
… now just install a cronjob, that checks withn the first days of the month, whether there is a fresh GeoIP db to fetch.
