title: How to repeat a few characters a few times in bash?
body: <p>In a bash script, I have to include the same file several times in a row as an argument. Like this:</p>
  
  <pre><code>convert image.png image.png image.png [...] many_images.png
  </code></pre>
  
  <p>where <code>image.png</code> should be repeated a few times.</p>
  
  <p>Is there a bash shorthand for repeating a pattern?</p>
