Anybody going to try set different desktop backgrounds in 10.9?

I'm using Greg Neagle's Python method.

Less obtrusive as doesn't restart the dock.

How exactly are you getting that to work? I ran into the stumbling block that Casper was running it as our management account. I'm not experienced enough with Python to try taking $3 and running the commands as that user.

I'm wondering the same thing as @franton. I haven't had success running it as a Launch Agent either. Also, that looks like it's choosing a random picture (or in my case I just hard coded a picture), but would still need a lot of logic needed to do something specific per user, based on group membership. I'm thinking I might just inject the db file with the pic I want into the User Templates and let everyone have the same one.

I may go the applescript route and scope accordingly.

osascript -e "tell application "System Events" to set picture of every desktop to "/Library/Desktop Pictures/pic.jpg""

EDIT: except that didn't work at all for me with no error messages ...

If you use the AppleScript option, use this.

osascript -e 'tell application "Finder" to set desktop picture to POSIX file "/path/to/image/file.jpg"'

and then Killall Finder or Dock, i don't remember what one I did before

I've tested the applescript route and checking the user group membership, then assigning a different pic based on that. What I don't like is the delay in it applying; the user logs in and sees a picture, which changes 3-5 seconds after login.

How exactly did you do that? I've tried a few things and they keep throwing applescript errors at me.

Seems its changed a little. You have to set the file path as a variable with a POSIX path, like so;

set desktopImage to POSIX file "Path/to/image.png"
tell application "Finder"
    set desktop picture to desktopImage
end tell
