title: Bash: How can I display the content of an environment variable from within a script?
body: <p>I can find lots of source about how to set environment variables but, i'm looking to display a variable rather than set it.</p>
  
  <p>I've wrote a custom <code>motd</code> file and I want it to display the <code>$LOCATION</code> environment variable in the output of the <code>motd</code> script, how is it done please?</p>
