simple question about mv

[Rob Smith]

HI,

 I know this is simple, but then again, so am I.  What if I want to mv a bunch
of files with the same suffix to another suffix. The following does not
work

    mv *.flip *.flop

what does?  I'm under Ultrix 2.2.  I'm doing it by hand, but I'd like to
be able to do wild card renames, ala DOS.


                                         Thanks,
                                            Rob.
