Empowering your long running PowerShell Automation Scripts with SMS/Text Notifications

18 months ago I wrote this post that detailed integrating Push Notifications into your scripts. That still works great, but does require that you have the associated Push Bullet application installed in your browser or on your devices. More recently I wrote about using Burnt Toast for Progress Dialogs’ for long running scripts. That too is all great if you are present on the host running those scripts. But what if you want something a little more native and ubiquitous? Notifications for those autonomous or long running scripts where you aren’t active on the host running them, and you don’t want the hassle of another application specific for that purpose? How about SMS/Text notifications?

This post details how to use Twilio (a virtual telco) from your PowerShell scripts to send SMS/Text alerts from your scripts so you can receive notifications like this;

Twilio is a virtual telco (amongst other products), that allows you to use services such as the mobile network via your application. For their SMS/TXT service they even give you a credit to get started with their service. To send SMS/TXT messages using their service from Australia each message is AU$0.0550.

Sign-up for a Twilio trial account, enable and verify your account. Take note of the following items as you will need them for your script;

  • service mobile number (initially Trial Number)
  • Account SID
  • your Auth Token

Using these pieces of information via the Twilio API we can send SMS/Text Notifications from your PowerShell scripts (well any language, but I’m showing you how with PowerShell). You can get your Service Number, Account SID and Auth Token from the Dashboard after registering for a Trial Account.

To enable SMS/TXT go to the Twilio Programmable SMS Dashboard here and create a New Messaging Service.

For my use (notifications from scripts) I selected Notifications, Outbound Only.

Once created you will see the following on the Programmable SMS Dashboard. That’s it, you’ve activated SMS/TXT in Trial Mode.

The Script

Here is a Send-TextNotification PowerShell Function that takes;

  • Mobile Number to send the notification to
  • Mobile Number the message is coming from
  • Message to send
  • AuthN info (Account SID and Account Token)
  • Account SID

Line 46 sends a SMS/TXT notification using my Send-TextNotification script. Update;

  • Line 32 for your Twilio Account SID
  • Line 34 for your Twilio Account Token
  • Line 40 for the mobile number to send the message to
  • Line 42 for the authorised number you verified to send from
  • Line 44 for your notification message


Using the Twilio service, my small function and a few parameters you can quickly add SMS/TXT notifications to your PowerShell scripts. Once you have it up and running I encourage you to upgrade your account and pay the few dollars for use of the service which also removes the “Sent from your Twilio trial account” text from the messages. Twilio also has a WhatsApp Notification Service.



PowerShell Progress Notifications that work in Visual Studio Code on Window 10

Earlier this year I made the switch from PowerShell ISE to Visual Studio Code (VSCode) and everything has been going just swimmingly. Well, until I was modifying some old scripts that perform some long running processes and I’d previously added Write-Progress statements in them to provide feedback as to how the script was going. Long story short, Write-Progress doesn’t work in VSCode. I’m definitely not the first to notice this as there is an open issue on Github for it, but seeing as its been open for 2 1/2 years I figured it probably wasn’t going to be resolved soon.

So I went looking for alternatives. I’ve found two that I’m happy with and will be using moving forward. One is a text-based console output progress bar and the other uses Windows 10/Windows Server Notification Centre. This post explores both and how I’m using them.


psInlineProgress is authored by Øyvind Kallstad and has been around for a few years now, so does require a small tweak to get it to work with VSCode. Nothing major, just a change for the Console (details further below). The progress bar itself is similar to the Write-Progress one in PowerShell. Here is an example;

inLineProgress Bar Notification
inLineProgress Bar Notification

You can get it from here if you need a manual install, otherwise it’s quick to install via Install-Module

Install-Module -Name psInlineProgress

To allow the progress bar to display in VSCode update the psInlineProgress.psd1 file to change Line 36 as shown below. You should be able to find it in C:\Program Files\WindowsPowerShell\Modules\psInlineProgress\1.1

#PowerShellHostName = 'ConsoleHost'
PowerShellHostName = 'Visual Studio Code Host'

Outputting to psInlineProgress

Updating the psInlineProgress bar is simply a case of giving the Progress Bar the dialog text you want displayed, in percent the progress, the progressed and un-progressed characters. In my example above I’m using the < symbol for the progress position, for the un-progressed and . for the progressed.  Sort of like a Pac-Man consuming dashes and outputting periods.

The PowerShell line looks like this, where $percentComplete is an integer between 0 and 100. E.g

Write-InlineProgress -Activity "Getting User Object $($obj.displayName)" -PercentComplete $percentComplete -ProgressCharacter '<' -ProgressFillCharacter '.' -ProgressFill '-'

Burnt Toast

Burnt Toast is a newer module writen by Josh King that takes advantage of new features in Windows 10. The progress notification isn’t a progress bar, but a Toast Notification via the Notification Centre. Here is an example;

Burnt Toast PowerShell Notification
Burnt Toast PowerShell Notification

You can get it from here if you need a manual install, otherwise it’s quick to install via Install-Module

Install-Module -Name BurntToast

Outputting to Burnt Toast

Updating Burnt Toast is similar to inlineProgress whereby you pass dialog text you want displayed, the progress completed as a fraction between 0 and 1, and a graphic. E.g

$ProgressBar = New-BTProgressBar -Status 'Getting User Objects' -Value $progressDisplay
New-BurntToastNotification –Text ‘IdentityNow Source Import’ -ProgressBar $ProgressBar -Silent –UniqueIdentifier 'Get Users' -AppLogo "C:\Users\DarrenJRobinson\Images\sailpoint.png"

As Burned Toast is a Windows Notification, after the toast notification disappears it can still be found in the Notification Centre.

Windows Notification Centre – Burned Toast

Other Burnt Toast Features

Burnt Toast can do much more, such as Alarms, Sounds and Reminders. See examples for those and more on Github here.

Working Example

Here is a working sample from a project where I’m processing thousands of identities. The $idnObjects is a PowerShell Object Collection of all the identities.

The following script snippet comes from the processing loop that processes the identities. $i is incremented on each loop (e.g $i++) and then used to calculate the percentage and fraction completed.

psInlineProgress and Burnt Toast are only updated each whole % of progress (that is calculated in line 9).

The output in VSCode therefore looks like the following. In reality you’d only have one or the other depending on what you were looking to achieve. I’ve done both together to show a side by side comparison.
