title: how to remove particular path in cygwin
body: <p>I want to ask how to remove path in cygwin. Let's say I have 3 paths:</p>
  
  <pre><code>PATH=path1:path2:path3
  </code></pre>
  
  <p>I want to remove path2 so it will be:</p>
  
  <pre><code>PATH=path1:path3
  </code></pre>
  
  <p>But actually i have a lot of path inside and it will painful to rewrite it manually. Any suggestion?</p>
