Add the following to your crontab (crontab -e):
* * * * * /Users/iain17/background.sh
- Create a file called background.sh (preferably in your home directory)
- Set the right location of the background.sh file in your crontab.
- Run the following command on the file, making it executable:
chmod +x /Users/iain17/background.sh
- Setup any fancy screenshot. I prefer this one: JohnCoates's Aerial screensaver
- Now every minute the background.sh shell script should check if the screensaver process is running. If it isn't it'll start it in the background, using your desktop wallpaper as output.
Enjoy!
