title: Why does using a pipe not work in powershell?
body: <p>I'm trying to execute the following line:</p>
  
  <pre><code>exit | sqlplus username/password@sid @test.sql
  </code></pre>
  
  <p>Works great from cmd but in powershell I get "An empty pipe element is not permitted"</p>
  
  <p>Why is this and how do I fix it?</p>
