title: Set an environment variable in git bash
body: <p>When I punch from the windows gitbash command line:</p>
  
  <pre><code>set $HOME = c
  </code></pre>
  
  <p>and do :</p>
  
  <pre><code>echo $HOME
  </code></pre>
  
  <p>It does not set it to <code>c</code>? How can I change/set the value of an environment variable?</p>
