#!/bin/bash

sqlite3 ~/Library/Application\ Support/Dock/desktoppicture.db "update data set value = '$1'" && killall Dock

Cron:

*/10 * * * * python /dir/to/himawari-8.py

I was thinking why you need all that logo_box stuff, until I saw you're covering the logo up, haha, good one.

I was getting:

Traceback (most recent call last):
  File "himawari-8.py", line 4, in <module>
    from PIL import Image
ImportError: No module named PIL

Fixed with:

sudo pip install image

Also, dir variable should contain full path to your folder (from the root), since the sqlite3 command will not receive relative paths.

And finally, to set the cron, try using crontab.

Haha, I felt bad about removing the logo! But I figured I'm not reproducing the image online without it (apart from in the screenshot!)

Ah yes, should have mentioned about that dependency.

Yup, dir should be full path. I'll update to make that more obvious.

Thanks for stopping by :)

I made this work on Linux Mint (Cinnamon) by changing just this line

    cmd = 'gsettings set org.cinnamon.desktop.background picture-uri "file:///' + dir + '/img/' + new_im_name+'"'
