title: replace multiple strings in one line with sed
body: <p>I have a list of packagenames and want to delete some of those with <code>sed</code></p>
  
  <pre><code>echo "package1 package2 package24 package44 package66 package12345" &gt; benoetigte_pakete.list
  </code></pre>
  
  <p>How can I delete some of those that are in another list?</p>
  
  <pre><code>dellist="package24|package66"
  </code></pre>
  
  <p>I tried </p>
  
  <pre><code>cat benoetigte_pakete.list | sed "s/(package24|package66)//"
  </code></pre>
  
  <p>but that doesn't work.</p>
