this is the code which will execute without checking for the file is empty or not.
This is the code which are executing by using crontab schedulers without checking whether the file is empty or not,because fo this we are getting many alert mails when ever it is executing empty file i.e., zero byte file.So we need to write a condition like

If File is empty not execute the command
else execute the file with the command.

Note:Files are present in this path /amex/abinitio/data_mount/GES/GlobalCapture/subm_I3/serial/queue/SubmDist/subscribe.SubmAPCD

It should pick the latest file check for zero byte if not execute the command with the file which we checked above.
