title: How to remove entry from $PATH on mac
body: <p>I was trying to install Sencha Touch SDK tools 2.0.0 but could not run it properly. It created an entry in the $PATH variable. 
  Later I deleted the sencha sdk tools folder but didn't realize that the path variable is still there. </p>
  
  <p>When i did <code>echo $PATH</code> I got -</p>
  
  <p><code>/Applications/SenchaSDKTools-2.0.0-beta3:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin</code></p>
  
  <p>I searched on how to remove variables from $PATH and followed these steps : </p>
  
  <ol>
  <li>Gave the command <code>PATH="/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin"</code></li>
  <li>Did <code>echo $PATH</code> which showed <code>/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin</code></li>
  <li>gave the command <code>export PATH</code></li>
  <li>Closed terminal and reopened it. Gave the command <code>echo $PATH</code>. This time I got 
  <code>/Applications/SenchaSDKTools-2.0.0-beta3:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin</code></li>
  </ol>
  
  <p>Can anyone tell me what am i doing wrong?</p>
