title: How do I place a dummy file in a git repo?
body: <p>I'm new at git so please bear with me. </p>
  
  <p>Say i have a file under version control that includes sensitive data. Sure enough, I put that file in my .gitignore file, so it doesn't get pushed to the repo. The problem now is somewhere in my project i have a line like</p>
  
  <pre><code>#include &lt;sensitivedata&gt;
  </code></pre>
  
  <p>or whatever your language of choice is. 
  The problem is whenever somebody clones from that repo, that file is missing and he gets a fatal error when trying to build / compile the solution.</p>
  
  <p>So, instead of pushing the file I'm actually working on I want to push some dummy file with the same name instead, where I place a comment like </p>
  
  <pre><code>// replace the next line with the sensitive data!!!
  </code></pre>
  
  <p>How would I do this?</p>
