Self Service Script to transfer Static Groups from old to new Mac

[MathiasO_TK]

Hey Guys,

no real Question but i saw some similar posts and questions or request for something like "$sbuject_title" ..

I want to share my solution for this scenario and perhaps some of you has an idea to optimize it:
User got new mac and wants to transfer all Static Groups from the old to the new mac.
I provide this script as policy in Self Service:

#!/bin/zsh

else
    # Create the folder
    mkdir -p "$TMP_DIR"
    
    # Check if the creation was successful
    if [ $? -eq 0 ]; then
        echo "The temporary folder has been successfully created at $TMP_DIR."
        
        # Set permissions (optional)
        chmod 755 "$TMP_DIR"
        echo "Permissions have been set to 755."
    else
        echo "Error: The folder could not be created."
        exit 1

# Catch Token
