This is a little bash script I wrote to fetch the latest Sinfest webcomic and places it on my Gnome desktop. It also formats the image to scale on Sundays using ImageMagick.
UPDATE: as of 7 December 2009 this script is licensed GNU/GPL v2
#!/bin/bash # fetch latest sinfest # set as gnome desktop # Copyright Jeff Channell 2009 # base url URL=`echo "http://www.sinfest.net/comikaze/comics/"` # name of file, based on date FILENAME=`echo "`date +%Y-%m-%d`.gif"` # where are we storing the images?

Then, to get it to run, I added this to my crontab:
0 */8 * * * /home/jeff/local/bin/desktop.bash > /dev/null 2>&1
UPDATE: I've been having some issues with cron not running lately as my user, but I also had Alarm Clock installed, so I just set a custom alarm to run my script there, and it's been working great ever since!
