title: tar: This does not look like a tar archive
body: <p>I split a huge folder:</p>
  
  <pre><code>tar cvpf - somedir | split -b 50000m
  </code></pre>
  
  <p>I then transfered split files to another server and merge it:</p>
  
  <pre><code>cat x* &gt; somedir.tar.gz
  </code></pre>
  
  <p>but when I tried to extract the file it shows errors:</p>
  
  <pre><code>tar xvf tar xvf somedir.tar.gz tar: This does not look like a tar
  archive tar: Skipping to next header tar: Archive contains obsolescent
  base-64 headers tar: Error exit delayed from previous errors
  </code></pre>
  
  <p>How to fix this problem?</p>
