Recently, I have been requested to write a small PowerShell script to fetch all the Azure resources with no tags at all, but I thought of writing a comprehensive script that is not only to find all the resources with no tags but also to find resources with specific tag name(s), tag value(s), tag(s), or with all tags.

Tagging in Azure

I have already covered Tagging Microsoft Azure Resources Using Powershell (Az) in my previous post, but just to brief…

Tags in Azure play pivotal role in managing the resources, predominantly in the cost governance strategies and much useful for automation and maintain environment hygiene. More than a resource name, tagging is very crucial and it must be consistent and appropriate across the resources in all the resource groups and subscriptions. Many organizations leverage the tagging effectively and consistently using the Azure policies or some automation techniques.

Find-AzResource

However, finding the resources in Azure is also crucial, and especially finding all the resources of all types from multiple subscriptions or resource groups. So I have come up with a PowerShell script to find all the Azure tagged/not tagged resources, and you can find the script in my GitHub repo…

The script comes with an in-build help, and if you run the script without any parameters it will display the help as below…
