How to set command output as env. variable in windows cmd?

I have saved azure storage key in key vault and i want to retrieve the key using Azure cli and set it as env. variable in window cmd before i run terraform script.

Below listed command doesn't work, can anyone tell me what needs to be changed ?

set ARM_ACCESS_KEY=$(az keyvault secret show --name terraform-backend-key --vault-name myKeyVault)

Error on initializing

enter image description here

Main.tf

variable "count" {}
variable "prefix" {
default="RG"
 }
terraform {
backend "azurerm" {
container_name       = "new"
storage_account_name  = "mfarg"
key                  = "terraform.tfstate"
}}
resource "azurerm_resource_group" "test" {
count ="${var.count}"
name     = "${var.prefix}-${count.index}"
location = "West US 2"
}

Command prompt output

A late answer, but perhaps useful to those who still have the same problem. This method will work in windows Command prompt, cmd. 

For /f %%i in ('az keyvault secret show --vault-name "Your-KeyVault-Name" --name "Your-Secret-Name" --query "value"') do set "password=%%i"

Now if you just run "echo %password%" you will see your secret value. Remember that az command has to be between ' ', like 'az keyvault secret etc'.

To set the environment variable in Windows, I suggest you use the PowerShell command to achieve it. In PowerShell, you can just do it like this:

$env:ACCESS_KEY=$(az keyvault secret show -n terraform-backend-key --vault-name myKeyVault --query value -o tsv)

Also, in your CLI command, you could not show the secret directly, it outputs the whole secret not just the access key as you want. See the difference between the two commands.
