Hey everyone I could really use some help. I’m trying to add installers to self service. I’m starting simple with Google Chrome. I’m new to scripting and Jamf and slightly confused.

What I’m trying to do is this: Uninstall the current version of Chrome; download an updated version of chrome; install updated version; add it to dock.

I found this article that helped but having an issue moving the DMG to the applications folder.

https://community.jamf.com/t5/jamf-pro/install-latest-version-of-google-chrome-without-re-packaging/m-p/156742#M145751

My uninstall script works like a charm:

#!/bin/bash

# This script can delete apps that are sandboxed and live in /Applications

# The first parameter is used to kill the app. It should be the app name or path

# as required by the pkill command.

applicationPath="$4"

if p> -z "${applicationPath}" ]]; then

    echo "No application specified!"

    exit 1

fi

## Closing Application

echo "Closing application: ${applicationPath}"

pkill "${applicationPath}"

## Removing Application

echo "Removing application: ${applicationPath}"

rm -rf "/Applications/${applicationPath}.app"

exit 0

Then I have this script for the reinstall:

#!/bin/sh

Points to the script in System Settings > Computer Management > Scripts

Alpha unistall google chrome = Before / Application Name = Google Chrome

Google Chrome Install Script = After

Dock Items:

Finally here is my problem:

I would be grateful for any advise or help. Please I'm a novice so nothing is to simple and I'm trying to learn to build more of these with other apps.
