UPDATE: I have added this script to my gitHub repo. You can find the freshest of the fresh here...

Hey everyone! It's been awhile since I've contributed anything to Jamf Nation.

I have a script / workflow that I've been sitting on since 2019 that I am finally ready to share...

I'm certain many of you use jamfHelper and for the most part, the jamfHelperGUI app is all but a dinosaur sitting on a couple of forked gitHubs out on the interwebs.

That being said, I got tired of writing jamfHelper pop-up windows for every workflow that needed one. I wanted something a bit more cookie-cutter... something I could drop into my Jamf Pro Scripts repository and call from within a policy by leveraging Jamf Pro's Scripts "Options" features.

So I set out to write a one-size fits all script to assist with the daily grind of pop-up communications.

So without further ado, I give you my latest iteration of jamfMessenger... version 3.x... oooh! shiny!

#!/bin/sh


##############################################################################
#
# FILENAME: jamfMessenger.sh
#
##############################################################################
#
# DESCRIPTION
#	Jamf Messenger is a script that allows a Jamf Admin to send pop-up messages
#	to end users/devices by leveraging the jamfHelper GUI application.
#
##############################################################################
#
# CHANGE CONTROL
#	v3.1 - 2022-05-25
#		Updated by Caine Hörr
#			Added a simplistic debug mode (more to come?)
#			Added examples for use with Jamf Script Options
#				Identified need for {} with values above 9 for Jamf Script Options
#			Added "Known Issues" section
#
#	v3.0 - 2022-05-24
#		Updated by Caine Hörr
#			Added ability to use UNICODE characters within pop-up windows
#			Added ability to use URL for pop-up icon image
#			Added countdownPrompt message
#			Added Message_Body_Line_4 message
#			Resolved issue with -lockHUD not being recognized
#			Resolved issue with -countdown not being recognized
#			Resolved issue with -fullScreenIcon not being recognized
#
#	v2.0 - 2021-08-10
#		Updated by Caine Hörr
#			Changed shebang from "bash" to "sh" to support zsh
#			Added additional lines for message body to support line breaks
#			Expanded code to utilize all features of jamfHelper
#
#	v1.0 - 2019-08-20
#		Written by Caine Hörr
#			Original script creation (jamf_Messenger.sh)
#
##############################################################################
#
# KNOWN ISSUES
#
#	UNICODE characters don't pass from Jamf Script Options to the final output
#		Currently requires hardcoding. <insert sad face here>.
#		I won't give up trying to make this happen!
#
#	Jamf Script Options are limited from ${4} through ${11}. You can't pass
#		ALL THE THINGS this way. I have a few ideas about how to get around
#		this limitation. Version 4.x perhaps?

As you can see, it's quite lengthy...

There's a lot of meat in this one.

Here's a screen capture of one of the pop-ups generated using some of the cool features contained therein...

Feel free to use it, hack it, whatever...

I just hope you find it useful...

Questions? Ask em if ya got em! I'll do my best to answer!

Until then... be well Jamf friends!

This is fantastic! Do you have a repo for this for community maintenance and also for ease of implementation?

cainehorr · ‎05-25-2022

~~I do have a personal gitHub account... I'm afraid I probably don't use it correctly though. Haven't take the proper time to learn gitHub. I probably should though!~~
