Probably not. If it were me, I'd put each group of files into its own directory, then use the rename command, e.g.:
cd ~/cam/wedding rename 's/^/wedding-/' *.jpg cd ~/cam/birth rename 's/^/birth-/' *.jpgThe 'rename' command for Debian is pretty powerful and dangerous. If you want to use it, read the manpage first.
