I am forever forgetting to delete Azure Resource Groups after I have finished with them, so I created the little PowerShell script below to help me clean them up. It works for all of your accounts Subscriptions too. This script could come in handy if multiple people are managing your Azure estate and not cleaning up after themselves.

I hope you find this script helpful. If you have any comments or questions please reach out.

The Script

#Log in to Azure account
Login-AzureRmAccount
#Get list of Azure Subscription ID's
$Subs = (get-AzureRMSubscription).ID
#Loop through the subscriptions to find all empty Resource Groups and store them in $EmptyRGs
ForEach ($sub in $Subs) {
Select-AzureRmSubscription -SubscriptionId $Sub
$AllRGs = (Get-AzureRmResourceGroup).ResourceGroupName
$UsedRGs = (Get-AzureRMResource | Group-Object ResourceGroupName).Name
$EmptyRGs = $AllRGs | Where-Object {$_ -notin $UsedRGs}
#Loop through the empty Resorce Groups asking if you would like to delete them. And then deletes them.
foreach ($EmptyRG in $EmptyRGs){
$Confirmation = Read-Host "Would you like to delete $EmptyRG '(Y)es' or '(N)o'"
IF ($Confirmation -eq "y" -or $Confirmation -eq "Yes"){
Write-Host "Deleting" $EmptyRG "Resource Group"
Remove-AzureRmResourceGroup -Name $EmptyRG -Force
}
}
}

I’m Richard Hooper aka Pixel Robots. I started this blog in 2016 for a couple reasons. The first reason was basically just a place for me to store my step by step guides, troubleshooting guides and just plain ideas about being a sysadmin. The second reason was to share what I have learned and found out with other people like me. Hopefully, you can find something useful on the site.
