Sending email based on file size

[sam93]

Hi,

I'm new to Unix environment, so I need help with this probably a simple task. I'm trying to send an email, based on the size (or existance) of a file, i.e., if the file is empty (or it dos not exist) on the given location, I don't need to send the email. However, if the file exists and is not empty, I have to send email.

How can I check if the file exists on the specified location and it's not empty.

Thanks for the help.

Try something like this:

if [ -s /path/to/file ]; then
  echo "OK"
else
  echo "Empty or non-existent"
file

FYI: man test

Hope This Help
