title: What is the preferred method to echo a blank line in a shell script?
body: <p>I am currently writing some code for a shell script that needs a blank line between two parts of the script, as thus they can be separated when output is displayed to the user. </p>
  
  <p>My question is, I am not sure what the preferred practice is in a shell script for a blank line. </p>
  
  <p>Is it preferred practice to just write <code>echo</code> and nothing else or to write <code>echo " "</code> as in echo with quotes and blank between the quotes?</p>
