title: How to specify a multi-line shell variable?
body: <p>I have written a query:</p>
  
  <pre><code>function print_ui_hosts
  {
  local sql = "select ........."
  print_sql "$ sql"
  }
  </code></pre>
  
  <p>local sql - a very long string. Query is not formatted.
  How can I split a string into multiple lines?</p>
