title: How can I trigger garbage collection on a Git remote repository?
body: <p>As we know, we can periodically run <code>git gc</code> to pack objects under <code>.git/objects</code>.</p>
  
  <p>In the case of a remote central Git repository (bare or not), though, after many pushes, there many files under <code>myproj.git/objects</code>; each commit seems to create a new file there.</p>
  
  <p>How can I pack that many files? (I mean the ones on the remote central bare repository, not on local clone repository.)</p>
