drock has asked for the wisdom of the Perl Monks concerning the following question:

I am running a system command to a file passing the data to a filehandle, but the if clause does not work. My goal is to run a system app command and if it creates a file greater than 0 bytes then use MIME:Lite to email the data otherwise just "touch" a file.Any ideas? thank you!
