title: How do I diff 2 Perforce Client Specs
body: <p>I have two perforce clients (client-a, client-b) that each contain about 40 file specs. They are similar, but each client has several file specs that aren't included in the other.   I would like to find the differences between these client specs.  Ideally, the output would look something like this...</p>
  
  <pre><code>File specs in client-a and not in client-b:
  //depot/dirA/...
  //depot/dirG/...
  
  File specs in client-b and not in client-a:
  //depot/dirD/...
  //depot/dirX/...
  </code></pre>
  
  <p>It would be nice if I could do something like <code>p4 diff -c client-a -c client-b</code> but after reading the documentation for <a href="http://www.perforce.com/perforce/doc.current/manuals/cmdref/diff.html" rel="nofollow noreferrer"><code>p4 diff</code></a> and <a href="http://www.perforce.com/perforce/doc.current/manuals/cmdref/diff2.html" rel="nofollow noreferrer"><code>p4 diff2</code></a>, this doesn't seem possible.  I could resort to writing an awk script, but thought there might be a better solution.  Is there an easy way to accomplish this?</p>
