I have some files on the Desktop


I want to copy those files to another folder like Destination but If the destination contains a file with same name I want to backup it to a folder named /Backup

So if a file named /Desktop/F1/T1 Already Exist on /Destination/F1/T1 it should be moved as Backup/F1/T1 I Need a Linux Script for this (actually Unix), The Command cp -b doesn't work on Mac.

Anything that you have tried ? – GajananH Nov 29 '12 at 8:47
This is very basic, at least try something yourself. This isn't a script request service! – iiSeymour Nov 29 '12 at 8:59

cp -n doesn't overwrite files that already exist.

cd ~/Desktop/
cp -Rn * ~/Destination/
cp -R * ~/Backup/

Try rsync with the --backup and --backup-dir flags.
