title: Find out where Google Cloud SDK is installed
body: <p>I need to add the Google Cloud SDK in the <code>PATH</code>. So I need the path to where is installed. Is there any <code>gcloud ...</code> command which gives me this information?</p>
  
  <p>If not I have to go through the symlink in <code>which gcloud</code>, etc.</p>
  
  <p>Any cleaner solution for this problem?</p>
