title: factor sudo across pipes
body: <p>I have this command line</p>
  
  <pre><code>$ sudo find /etc/grub.d | sort | tail -n 1 | xargs sudo cat | wc
  </code></pre>
  
  <p>that I want to execute with a single sudo command</p>
  
  <pre><code>$ sudo --some-how "find /etc/grub.d | sort | tail -n 1 | xargs cat | wc"
  </code></pre>
  
  <p>such that the entire command line is run as root.</p>
