title: See continuous logging on command line
body: <p>I am currently working on a Firebase function. As I am still in the development stage, I have a number of logs in my code to see what's going on.</p>
  <pre><code>async function getAddressByIdAsync(address) {
  
      let addr = addressesRef.child(address);
      console.log(addr);
  
      return admin.database().ref('Addresses/' + address);
  }
  </code></pre>
  <p>The only way I have found to be able to see these logs in real time is though the Firebase console, which is very slow and generally a bad UI experience IMO.</p>
  <p>I'm looking for a command line solution that will let me see in real time the logs coming from the Firebase cloud function.</p>
  <p>I have tried this command</p>
  <pre><code>firebase functions:log
  </code></pre>
  <p>Which appears to return the last twenty or so log entries into my Firebase Functions.</p>
  <p>I know Google Cloud has a tail option on the end of that CLI but it doesn't work here.</p>
  <pre><code>firebase functions:log tail
  </code></pre>
  <blockquote>
  <p>Error: Too many arguments. Run firebase help functions:log for usage instructions</p>
  </blockquote>
  <p>Is there a way to get a live running output of the logs from firebase cloud functions?</p>
