title: "No such file or directory" when executing Perl script
body: <p>I have a 3D modal for cup.obj. I need to convert to .h file so I downloaded this <a href="http://heikobehrens.net/2009/08/27/obj2opengl/" rel="nofollow">http://heikobehrens.net/2009/08/27/obj2opengl/</a> And put cup.obj file to this folder. Then I run from terminal obj2opengl.pl cup.obj I didn't get .h file.</p>
  
  <pre><code>Ranganatha-GVs-Mac-mini:~ ranganathagv$ ./obj2opengl.pl cup.obj
  -bash: ./obj2opengl.pl: No such file or directory
  Ranganatha-GVs-Mac-mini:~ ranganathagv$
  </code></pre>
