Hi all techie geniuses,

I am new to the tehc field and need some help badly.
I need a ksh script. Every time a file is dropped in a folder, there should be a script running at all times. What this script does is, simply copies this file in a different folder with timestamps as part of the new file name. The script should be smart enough to not copy the same file over and over, but just copies new files every time its dropped. I will highly appreciate if you can write this script for me in detail, as I do not understand anything when it comes to scripts. Thanks in advance
