title: quote around the output value using terraform "local-exec" provisioner
body: <p>I want to put the quote around the output value(in simple, I want to write the output to the file using "local-exec" provisioner but unfortunately it didn't put the quote around it although it did echo the correct value to the file. I have also used the escape character () but still no luck. Any help will be highly appreciate. Thanks</p>
  
  <p>code snippet for reference:</p>
  
  <pre><code>provisioner "local-exec" {
  command = " echo **ELB_DNS_NAME: \"${aws_elb.elb.dns_name}\"** &gt;&gt; ${var.name}.yml"
  }
  </code></pre>
