title: How to extract tar archive from stdin?
body: <p>I have a large tar file I <code>split</code>. Is it possible to <code>cat</code> and untar the file using pipeline.  </p>
  
  <p>Something like:</p>
  
  <pre><code>cat largefile.tgz.aa largefile.tgz.ab | tar -xz
  </code></pre>
  
  <p>instead of:</p>
  
  <pre><code>cat largefile.tgz.aa largfile.tgz.ab &gt; largefile.tgz
  tar -xzf largefile.tgz
  </code></pre>
  
  <p>I have been looking around and I can't find the answer. I wanted to see if it was possible.</p>
