title: Why set VISIBLE=NOW in /etc/profile?
body: <p>I'm reading a <a href="https://docs.docker.com/engine/examples/running_ssh_service/" rel="noreferrer">Dockerfile - Dockerizing an SSH Service</a> and it contains the following code:</p>
  
  <pre><code> ENV NOTVISIBLE "in users profile"
   RUN echo "export VISIBLE=now" &gt;&gt; /etc/profile
  </code></pre>
  
  <p>Just curious what the purpose of that is?</p>
  
  <p>TIA,
  Ole</p>
  
  <p>P.S Great article here on ways to avoid running an SSH Server in a Docker container: <a href="https://jpetazzo.github.io/2014/06/23/docker-ssh-considered-evil/" rel="noreferrer">https://jpetazzo.github.io/2014/06/23/docker-ssh-considered-evil/</a> </p>
