export is not recognize in cmd while Cygwin is installed
<p>My machine is running win7 64bit. I installed Cygwin and added <code>C:\cygwin64\bin</code> to the <code>PATH</code>. Now linux commands work on cmd , but <code>export</code> is not recognized:</p>

<blockquote>
  <p>'export' is not recognized as an internal or external command,
  operable program or batch file.</p>
</blockquote>

<p>while it works properly in Cygwin64 Terminal. How should I add it to windows default cmd?</p>
