title: Exclude permission denied messages from find
body: <p>In bash, I can redirect stderr using 2>&amp;1 with the <code>find</code> command and pipe it to <code>grep</code> to remove any <code>Permission denied</code> messages. How do I do this in csh? I am getting the error message <code>Ambiguous output redirect</code>. I have already tried the syntax at this <a href="https://stackoverflow.com/questions/762348/how-can-i-exclude-all-permission-denied-messages-from-find">question</a>, and it gives me the error described.</p>
