timbit! Simple bash script to get NASA's Astronomy Picture of the Day

1. Add this script to your crontab (I run it hourly)
2. Set your wallpaper preference to ~/images/wallpapers/apod.jpg (or edit APOD_FILE below)
3. The next time you log in the new image will appear

#!/bin/bash

BASE_URL=http://apod.nasa.gov/apod/
PAGE_URL=${BASE_URL}/astropix.html
APOD_FILE=~/images/wallpapers/apod.jpg

wget -qO - ${PAGE_URL} | grep "IMG" | \
    wget -qO ${APOD_FILE} \
    ${BASE_URL}`awk -F "\"" '{print $2}'`
