Here's a sample of my script below. Lines 1 to 11 are the information about the script. Lines 12 to 16 are the setup for some of the instructions on my script. Lines 17 to 23 are kind of like a check point to determine if the script should continue executing or if it should end right there. My issue is that the steps following the check point are being executed and are producing a false email at the end of the script. I would like to stop the email from going out if the script didn't find any files in the source directory, See my script below.
