title: How do I replace a token with the result of `pwd` in sed?
body: <p>I'm trying to do something like this:</p>
  
  <pre><code>sed 's/#REPLACE-WITH-PATH/'`pwd`'/'
  </code></pre>
  
  <p>Unfortunately, I that errors out:</p>
  
  <pre><code>sed: -e expression #1, char 23: unknown option to `s'
  </code></pre>
  
  <p>Why does this happen?</p>
