title: Executing command with powershell
body: <p>Beginner question power shell.
  How can I execute a command with an @ in it in powershell?
  This works fine in a dos window:</p>
  
  <pre><code>curl --ntlm -d @somejson_ok.json --header `"Content-Type: application/json`" -u : -X POST http://localhost/someaction
  </code></pre>
  
  <p>How can I run this with powershell? I tried:</p>
  
  <pre><code>$command = "curl --ntlm -d @somejson_ok.json --header `"Content-Type: application/json`" -u : -X POST http://localhost/someaction"
  iex $command
  Read-Host "Done"
  </code></pre>
  
  <p>Error: Der Splat-Operator "@" kann nicht dazu verwendet werden, auf Variablen in einem Ausdruck zu verweisen.
  Help appreciated :)</p>
