Unlike DOS file extensions, the '.' is just another character to unix.
How about:  (using /bin/sh)

for i in *.flip
do
mv $i `sed -e 's/flip$/flop'`
done

It might be easier to arrange to have flip and flop subdirectories instead
of using the file suffix since it is a bit easier to:
  mv flip/* flop
and generally no more difficult to construct the full pathname.
