Notify Users with a dialog (macOS)

Description 
 The provided Fileset is an example of notifying users, in particular, a message regarding the Fileset status when downloading and installing new Filesets. 
 
  The Fileset is designed to: 
 
 Create a continually running service that monitors Fileset changes 
 Where Fileset changes occur, begin monitoring the FileWave Client log file 
 If the preset text strings are found in the log file, send this to the Notification Centre 
 Lastly, where another preset text is found, stop monitoring the log file 
 
 The service has been built to be actioned automatically by the user logging in.  Where Filesets are disassociated, each has a pre-uninstallation script to ensure that the services are also removed. 
 Ingredients 
 
 Provided Fileset: 
 
 
 
 
 
 ↓ macOS 
 
 
 
 
 
 
 
 
 
 Directions 
 For the example provided: 
 
 Download the necessary provided Fileset 
 Upload using FileWave Admin 
 Create a Deployment to the appropriate devices 
 'Update Model'. 
 
 Fileset scripts may be modified for personal preference.  In each Fileset, there is a script that is executed by the local computer service.  The scripts are using a pattern match.  The pattern matching may be edited as required, removing or adding appropriately. 
 
 macOS 
 Locate the "prompt_user.sh" file within the Fileset and choose to edit.  In the following code block snippet from this script, the case statement is pattern-matching text.  In the provided example, the script is looking for lines that contain any one of the following: 
 
 Model version 
 Downloading Fileset 
 Done activating 
 Activate all 
 
 Where found, the 'show_message' function is being used to prompt the user: 
 prompt_user.sh 
 # * are wildcard entries and | acts as a logical OR
case "$line" in
		*"Model version"*|*"Downloading Fileset"*|*"Done activating"*|*"Activate all"*)
			show_message
			;; 
 The second part of the case statement is causing the script to exit.  The pattern match this time is any line that contains: 
 
 Data successfully sent to the inventory server 
 
 prompt_user.sh 
 *"Data successfully sent to the inventory server"*)
			exit 0
			;; 
 Notification Center Permissions 
 Notifications are a user's choice.  Users must accept notifications when prompted. 
 The section below of the 'com.filewave.promptuser.plist' may be edited as desired, where the defined keys determine the following: 
 
 'the_title' is the Title of the notification 
 'bundle_id' defines an App bundle.  That bundle's name and icon will be displayed: 
 
 
 com.filewave.prompt_user.plist 
 <key>EnvironmentVariables</key>
	<dict>
		<key>the_title</key>
		<string>FileWave Message</string>
		<key>the_subtitle</key>
		<string></string>
		<key>bundle_id</key>
		<string>com.filewave.fwGUI</string>
	</dict> 
 Users may still allow Notifications in System Preferences if previously denied: 
 
 Launch Services Once a launch service is running, editing an already loaded script will have no impact on the current service; the service itself must be reloaded.  If parts of the Fileset are edited after association, consideration should be taken into account to ensure those changes are made active. 
 Notes 
 The above provides an example of notifying users using a service.  However, with some adaptation, messages could be sent in other ways at alternate times to users.
