Set Desktop Wallpaper from Command Line on Mac

By  on  

Whenever I need to accomplish a basic task that typically calls for interacting with a UI, I challenge myself to complete the task from command line. After all, most UIs are simply a mask over basic commands, especially when it comes to the operating system. Suddenly I feel like an automation or systems engineer!

One task I can imagine an IT administrator would need to automate is setting the desktop wallpaper via a script, remotely, or simply by providing the command to do so:

osascript -e 'tell application "Finder" to set desktop picture to POSIX file "/Users/davidwalsh/Downloads/pubg-background.jpg"'

It's important to note that you must provide the absolute path to the image, and not a path that begins with a user path (i.e. ~/Downloads/my-image.jpg)

Beyond the general nerdiness of knowing how to change desktop wallpaper via command line, it could be useful to change your background based on a service being down or other event.

I challenge you to think more like a remote IT administrator or automator when you need to accomplish your next simple task!
