title: Replacing variables into a multiline shell variable
body: <p>I'm building an email message by reading some rows from a database into a multiple line shell variable called EMAIL_DESC:</p>
  
  <pre><code>EMAIL_DESC=`run "select text from  ETL.MAIL_TEXT where ID=1 order by id, text_order"`
  </code></pre>
  
  <p>Unfortunately I have variables and commands (<code>date</code>) inside $EMAIL_DESC but I can't substitute them in any way.</p>
  
  <pre><code>echo "$EMAIL_DESC"
  Please be aware that all user tables and views on the $SERVER_DESC
  Ended = `date`.
  </code></pre>
  
  <p>Any idea?</p>
