title: How to read output from bzcat instead of specifying a filename
body: <p>I need to use 'last' to search through a list of users who logged into a system, i.e.</p>
  
  <pre><code>last -f /var/log/wtmp &lt;username&gt;
  </code></pre>
  
  <p>Considering the number of bzipped archive files in that directory, and considering I am on a shared system, I am trying to include an inline bzcat, but nothing seems to work. I have tried the following combinations with no success:</p>
  
  <pre><code>last -f &lt;"$(bzcat /var/log/wtmp-*)"
  last -f &lt;$(bzcat /var/log/wtmp-*)
  bzcat /var/log/wtmp-* | last -f -
  </code></pre>
  
  <p>Driving me bonkers. Any input would be great!</p>
