Save the Bing image of the day to your device, from the commandline!
Ensure you have jq installed.
Use the script simply by calling it.
./bing-image.sh or bash bing-image.sh
For a desktop environment, such as Gnome, and some window managers, there are other tools to set the bing image as the wallpaper, for example this and this.
The difference between those and this project is that this one doesn't set the wallpaper, it only installs the image and allows you to choose what to do with it. I use it with Sway, since those I mentioned do not seem to support Wayland window managers.
For example with Sway, adding this to the end of the file causes the background image to be changed:
swaybg -i $file -m fill
