title: Managing many git repositories
body: <p>Setting up a project is easy in git and so I can have separate repository even for small script. Now the problem is how to manage them.</p>
  
  <p>I work in multiple places with these repositories. When I have done changes to some repository, I want to be able to update the repositories in other places.</p>
  
  <p>So I have a directory with many repositories in it.</p>
  
  <ol>
  <li>How can I fetch all of them?</li>
  <li>How can I check whether any of them have uncommitted changes?</li>
  <li>How can I check whether any of them have changes to merge?</li>
  </ol>
  
  <p>And it would be nice to be able to do these with one command.</p>
  
  <p>The output needs to be silent enough to actually notice the things to do.</p>
