  </code></pre>
  
  <p>The file actually has many of these entries and I want to get the following file</p>
  
  <pre><code>nimbox-apexer-sales 1.0.0-201007241449
  nimbox-tomcat 6.0.26-5
  </code></pre>
  
  <p>Where the <code>Package</code> and the <code>Version</code> are separated by a <code>tab</code> so that I can later use <code>cut</code> to get them.  I'm pretty sure this can be done with <code>sed</code>.  I went over the sed one liners but this is probably a bit more complex.  Any ideas?</p>
