Which OSs does this script support?

And also the title is misleading, script only changes the background image. Cron job or scheduler is needed to do a periodic run/update of bg.

Linux

The install.sh script includes crontab setup. Why should it bundle its own scheduler when there’s a perfectly fine one included on the OS?

Hey , this script was not present in the repo when I made that comment. Good to see that they have included shell script.

What a coincidence. Last week I wrote a script to update my gnome background image once a day from APOD (Astronomy Picture of the Day).

Didn't put on GH, though.

It uses a third party app to change the background image.

On Mac I’ve done this in the past with

defaults write com.apple.desktop Background '{defaults = {ImageFilePath = "$PathToImage"; };}';

think it's compatible with ultrawide screen (5120x1400)?

yes! If you use feh it should center the earth on your monitor. Didn't test it on ultrawide screens thoug.

i will definitely try it when I get home later this week! I'll let you know if it works!
