title: Redirecting stderr in csh
body: <p>I'm executing a program that dumps crash report into <code>STDERR</code> from where I have to filter some necessary information. The problem is that I'm unable to redirect <code>STDERR</code> to <code>STDOUT</code> and <code>PIPE</code> it with <code>grep</code></p>
  
  <pre><code>command 2&gt;&amp;1 &gt;/dev/null | grep "^[^-]" &gt;&amp; /tmp/fl
  </code></pre>
  
  <p>Getting error: <code>Ambiguous output redirect.</code></p>
  
  <p>Same command works under bash terminal.
  What should I change to make it work ?</p>
