                                                  [--set]. The 1th example of the child command would be to use it to 'enable change feed and set change feed retention days to infinite for the storage account  mystorageaccount  in resource group  myresourcegroup', the syntax is: az storage account blob-service-properties update --enable-change-feed true -n mystorageaccount -g myresourcegroup. The 2th example of the child command would be to use it to 'enable change feed and set change feed retention days to 100 for the storage account  mystorageaccount  in resource group  myresourcegroup', the syntax is: az storage account blob-service-properties update --enable-change-feed --change-feed-days 100 -n mystorageaccount -g myresourcegroup. The 3th example of the child command would be to use it to 'disable change feed for the storage account  mystorageaccount  in resource group  myresourcegroup', the syntax is: az storage account blob-service-properties update --enable-change-feed false -n mystorageaccount -g myresourcegroup. The 4th example of the child command would be to use it to 'enable delete retention policy and set delete retention days to 100 for the storage account  mystorageaccount  in resource group  myresourcegroup', the syntax is: az storage account blob-service-properties update --enable-delete-retention true --delete-retention-days 100 -n mystorageaccount -g myresourcegroup. The 5th example of the child command would be to use it to 'enable versioning for the storage account  mystorageaccount  in resource group  myresourcegroup', the syntax is: az storage account blob-service-properties update --enable-versioning -n mystorageaccount -g myresourcegroup. The 6th example of the child command would be to use it to 'set default version for incoming request for storage account  mystorageaccount', the syntax is: az storage account blob-service-properties update --default-service-version 2020-04-08 -n mystorageaccount -g myresourcegroup. The parameter '--account-name -n' is required. It is used to the storage account name.. The parameter '--blob-services-name' is required. It is used to the name of the blob service within the specified storage account. blob service name must be 'default'. "default" required..
