title: BASH script to check PDF's are ocr'd
body: <p>Don't know where to start on this really </p>
  
  <p>I have a linux server with over 8000 PDf's and need to know which PDF's have been ocr'd and which one's haven't. </p>
  
  <p>Was thinking some sort of script calling XPDF to check the pdf but to be honest not sure if this is possible </p>
  
  <p>Thanks in advance for any help    </p>
