title: git submodule foreach: execute read
body: <p>Is it possible to execute a read inside a git foreach?</p>
  
  <pre><code>git submodule foreach 'read -p "test"; echo $REPLY'
  </code></pre>
  
  <p>does not work at all as the read gets the input from git itself - which is the objname and hash here.
  Is there any chance to read interactively of the console?</p>
