title: How to run ./script.sh in windows Git shell?
body: <p>Maybe it's awkward, but I can't run .sh file on Windows when working in Git shell. Probably I have to install something, but I thought that Git will support that bash command (I know Windows don't use sh files).</p>
  
  <p>I am doing installation steps from <a href="http://docs.gameclosure.com/guide/install.html" rel="noreferrer">GameClosure</a> and after <code>$ ./install.sh</code> a window with application selection to open sh file appears (like that when you try to open unknown file in Windows, it asks what application to open this you would like to use).
  I've tried open it with Git shell, but failed... <strong>What I have to do to run this file</strong> and proceed with installation steps from GameClosure tutorial?**</p>
  
  <p>Here is a screenshot (alert in polish, but I think you all know this message).
