Autochange Wallpaper from Unsplash

This simple shell script runs every hour and takes an image from Unplash.com and sets it as a wallpaper. You can choose whatever wallpaper you want by changing the URL in wget of the shell script.

Go to source.unplash.com to know more about the Unplash API.

Installation

• Place this script in your /bin directory.
• Open your terminal and make it executable with sudo chmod +x /bin/unsplash.sh
• Run it using ./unsplash.sh
• This will add the cronjob automatically and set your wallpaper.

NB: If you change your script name from unsplash.sh to anything.sh, rename the file name in the code.

unsplash.sh

#/bin/bash

echo "Getting wallpaper from collection."
wget -O /tmp/wallpaper.jpg https://source.unsplash.com/collection/1166960/1920x1080
gsettings set org.gnome.desktop.background picture-uri file:///tmp/wallpaper.jpg
echo "Wallpaper set."

# Now set cronjob of an hour
echo "Setting cron to change wallpaper every hour"
if crontab -l | grep "unsplash.sh"; then
  echo "Cron exists. Continue to run normally."
else
	(crontab -l ; echo "0 * * * * /bin/unsplash.sh") | crontab -
	echo "Cron set. Wallpaper will change every hour now."
