title: Check if file exist with current date
body: <p>I have an backup tool that runs every day on 2 am, 
  The backup output saved under existed folder named "collector"</p>
  
  <p>i'm trying to write script bash, 
  That will check if folder named "repository" exist under the "collector" directory with the current/today date. (i.e in compare to the RHEL date) </p>
  
  <p>in case folder exist with older date, send email using echo.  </p>
