In order to delete all resource groups that start with project01, for example, you’ll first need to make sure you’re in a Bash shell and not PowerShell. Then, type:
az group list --query "[?starts_with(name,'project01')].[name]" --output tsv | xargs -L1 bash -c 'az group delete --name $0 --no-wait --yes'
In order to list all resource groups that start with rg, for example, type:
az group list --query "[?starts_with(name,'rg')].name" --output tsv
