@JAMFNoob That command relies on being run as the logged in suer, and if you're running it via a script or a files & process command in a Jamf Pro policy that doesn't run as the logged in user. To see how to run a command as the logged in user take a look at the following blog post: https://scriptingosx.com/2020/08/running-a-command-as-another-user/

In this particular case you may be better creating a LaunchAgent on the local Mac. LaunchAgents run in the user context.

Could you try this?

#!/bin/bash

currentuser=$(/usr/bin/who | awk '/console/{ print $1 }')
/usr/bin/osascript > /dev/null << EOT

tell application "Finder"
activate
mount volume "smb://server/staffhome$/${currentuser}/"

end tell

EOT

This didn't work for me - although I did try the below but still failing to get to the user's folder, just takes me to the staff directory above it

currentUser=$( echo "show State:/ Users/ConsoleUser" | scutil | awk '/ Name { print $3 }' )
open "smb://server/staffhome$/$currentUser"

Your script isn't running in the user context, when jamf executes it, it's run as root.

sudo -u $currentUser open "smb://server/staffhome$/$currentUser"

Might work...
