title: Using file contents as command line arguments in BASH
body: <p>I'd like to know how to use the contents of a file as command line arguments, but am struggling with syntax.</p>
  
  <p>Say I've got the following:</p>
  
  <pre><code># cat &gt; arglist
  src/file1 dst/file1
  src/file2 dst/file2
  src/file3 dst/file3
  </code></pre>
  
  <p>How can I use the contents of each line in the <code>arglist</code> file as arguments to say, a <code>cp</code> command?</p>
