title: How to open .bashrc in Cygwin
body: <p>When I try to compile my Android NDK program, it shows the following error:</p>
  
  <pre><code>Program "${SA}\android-ndk-r8\ndk-build.cmd" not found in PATH  
  </code></pre>
  
  <p>(the value of the environment variable "SA" is C:)</p>
  
  <p>I am using Cygwin on Windows 7. How do I open my <code>.bashrc</code> file? I read that I need to add the following lines to my <code>.bashrc</code> to fix the problem:</p>
  
  <pre><code>NDK_HOME=/opt/android-ndk-r8
  
  
  export NDK_HOME
  </code></pre>
  
  <p>But I am not sure how to open <code>.bashrc</code> and edit the file as I have never done this before.</p>
