I am using a for loop to copy files from say DIR1 and DIR2 to DIR3.I have to check whether files are copied from DIR1 and DIR2 and print the respective message.
The above script works fine in perl but not working in perl web service.In perl web service the copy commands are executing but I am not able to print message for each directory individually.
Any help would be appreciated.
Thanks,
Liyakath.
