title: Check if multiple files are empty in single if statement
body: <pre><code>awkOut1="awkOut1.csv"
  awkOut2="awkOut2.csv"
  if [[ "$(-s $awkOut1)" || "$(-s $awkOut2)" ]]
  </code></pre>
  
  <p>The above 'if' check in shell script gives me below error:</p>
  
  <pre><code>-bash: -s: command not found
  </code></pre>
  
  <p>Suggestions anyone?</p>
