Set a desktop Pic using script (profile won't let user change it)

Trying to run this as the user but im losing my mind:

 osascript -e 'tell application "Finder" to set desktop picture to POSIX file "/Library/Desktop Pictures/Solar Gradients.heic

I just want to wrap that in a shell and have it use the logged in user to run it. I know I've done this before...but I can't seem to do it right now.

Ive been playing with profiles managing the desktop pic, however this seems to lock it and won't let the user change it which Im not fond of.
Any other solutions would be wonderful if anyone has any.

You may want to have a look at the desktoppr tool. Very useful, I deploy it everywhere, much better than dealing with AppleScript intricacies πŸ™‚

edit: crap you need the set the desktop instead..

try below script?

i vaguely remember that you need to run sudo killall cfprefsd to apply the changes.

#!/bin/sh

# grab current user
curUser=`ls -l /dev/console | cut -d " " -f 4`

# grab the system's uuid
if [[ `ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c27-50` != "00000000-0000-1000-8000-" ]]; then
    macUUID=`ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c27-62`
fi

#jamf displayMessage -message $curUser
defaults write /Users/$curUser/Library/Preferences/ByHost/com.apple.screensaver.$macUUID.plist PrefsVersion -int 100

# Use below to deploy custom screensaver
#defaults write /Users/$curUser/Library/Preferences/ByHost/com.apple.screensaver.$macUUID.plist moduleDict -dict moduleName "SOMETHING" path "/path/to/file" type -int 1

chown "$curUser" "/Users/$curUser/Library/Preferences/ByHost/com.apple.screensaver.$macUUID.plist"

sudo killall cfprefsd

#allow all users access to Folder where the Screensaver is
chmod -R 0777 /path/to/file

Maybe I can wrap my AppleScript in your shell script though.
Thanks for the fast reply!

This should get you what you're looking for.

#!/bin/sh

picLoc="/Path/To/Your/Wallpaper.jpg"
currentUser=$(/bin/ls -l /dev/console | /usr/bin/awk '{print $3}')

#Replace the Current Picture
sudo -u "$currentUser" -H osascript -e "tell application "Finder" to set desktop picture to POSIX file "$picLoc""
