Copy Azure Permissions
I was replacing an old service account with a service principal, and needed to replicate the permissions in Azure. I was able to do that without missing anything, using the command below. $CopyFrom = 'Object to copy from' $CopyTo = 'Object to copy to' Get-AzRoleAssignment -ObjectId $CopyFrom | ForEach-Object{ New-AzRoleAssignment -ObjectId $CopyTo -RoleDefinitionId $_.RoleDefinitionId -Scope $_.Scope }
Reboot remote computer and wait
This script that will send a reboot command to a remote computer. It will then monitor for it to go offline and then come back online.

Testing and Deploying ARM Templates
I often find that when building an ARM template, I need to test it multiple times. So, I created the script below that will create the resource group (is it doesn’t exist), run the test cmdlet (and stop if there is a problem), and deploy the template to Azure. It will create a new name for the deployment each time...

A Quick Lesson in Boolean

While this technically will work for Boolean values, there are situations where this will not work. For example, if you pass the string value of “False” to the statement above it will evaluate as True. This is because the if condition in...
Fast Deploy Microsoft Teams for Education
Recently one of my colleagues came to me with an interesting situation. His wife runs a homeschool co-op. Basically, a group of parents who homeschool their children, with different parents covering different subjects. Due to COVID-19, he needed a quick way to get them setup in Office 365 and Teams. So, I put together a quick upload script to import...
Properly Capitalize a Title Using PowerShell
Being married to someone who majored in English has made me extra conscious of my spelling and capitalization. So, for my blog posts, I’ve written a script to help me ensure my titles are properly capitalized. It is not perfect (i.e. it doesn’t do a dictionary lookup), but it follows the basic APA guidelines.
