title: How to short or hide the git repository's absolute path by ssh protocol?
body: <p>I am building a git server on Ubuntu. </p>
  
  <p>On the git server, I create a git repository on /opt/var/git/example.git.
  When a client wants to clone this git repository, he should use the command "git clone ssh://username@host-ip/opt/var/git/example.git"</p>
  
  <p>I wonder if there is any way to short the ssh path and hide the absolute path.</p>
  
  <p>For example, the client could clone "example.git" by 
  "git clone ssh://username@host-ip/example.git".</p>
  
  <p>Thanks!</p>
