For this functionality I suggest using rsync which already implements this capability. rsync -n -av /mnt/usb/thumb/ tmp/androidBackup/SDCard/thumb/ I see you using cp -i but if you are going to be copying megabytes and many files I assert that cp -i isn't a good practical way to ensure a good result. But rsync --ignore-existing and --update options are available for data merging. Bob
