How to delete all Azure resource groups except one

Question

I want to delete all the the resource groups except the one used by cloud shell.

$ az group list --query [].name --output tsv | grep -i -v cloud >> resGroups.txt

$ while read RGS; do echo $RGS;done<resGroups.txt
DefaultResourceGroup-EUS
NetworkWatcherRG

$ while read RGS; do az group delete -n $RGS --no-wait -y;done<resGroups.txt
validation error: Parameter 'resource_group_name' must conform to the following pattern: '^[-\\w\\._\\(\\)]+$'.
validation error: Parameter 'resource_group_name' must conform to the following pattern: '^[-\\w\\._\\(\\)]+$'.

$ while read RGS; do echo $RGS | sha256sum ;done<resGroups.txt

$ echo DefaultResourceGroup-EUS | sha256sum

Based on the error and just doing an echo, it's looking like the loop is working but there's something wrong with how the names are getting printed to the file.

I don't understand why the hashes don't match.

xxxxxxxxxxxxxxxxxxxxxxxxxxxxx SOLUTION xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Thanks to everyone for their input, it got me thinking and I realized the issue is how I'm outputting the string.

This doesn't work because it adds a tab at the end of each string:

notRG=$(az group list --query "[?contains(name, 'cloud')].name" --output tsv)

This will delete every resource group in your Azure account except any that include the word cloud:

notRG=$(az group list --query "[?contains(name, 'cloud')].name" --output json | jq .[] -r)
for i in $(az group list --query "[?name!='$notRG'].name" --output json | jq .[] -r); do az group delete -n $i -y; done

When I kicked off the loop:

$ az group list | grep -i "name\|state"
    "name": "myResourceGroup",
      "provisioningState": "Deleting"
    "name": "DefaultResourceGroup-EUS",
      "provisioningState": "Succeeded"
    "name": "MC_myResourceGroup_myAKSCluster_eastus",
      "provisioningState": "Deleting"
    "name": "NetworkWatcherRG",
      "provisioningState": "Succeeded"
    "name": "cloud-shell-storage-westus",
      "provisioningState": "Succeeded"

After the loop completed:

$ az group list | grep -i "name\|state"
    "name": "cloud-shell-storage-westus",
      "provisioningState": "Succeeded"

Not sure if there is a reason you are using outputting the first part to a file. Have you looked into JQ. It's great for processing json, and you can do loops straight from it. So you could easily save the JSON to a file and have it processed by JQ and use it for a loop. https://starkandwayne.com/blog/bash-for-loop-over-json-array-using-jq/ — Ron, Jul 14 '20 at 03:59

Delete resource group with name:

az group delete --name ExampleResourceGroup

I have tried !("groupName") and ^((?!groupName).)*$ to replace ExampleResourceGroup, but the error(validation error) is still reported.

So I use the if-statement to except. You could add the code in the loop.

groupName='xxxxxxxx';
if [ $groupName!='the group name that you want to except' ]; then az group delete -n=$groupName; fi;

I try this with az group show, and it works well.

This didn't work for me either :( It turns out the issue is with how the Azure CLI outputs the string. – Aaron Jul 15 '20 at 16:14
