certainly:
I have it assigned to an alias as:
lc;exiv2 mv \-k \-r %y%m%d_%H%M%S_:basename: \.\/*.{nef,jpg}
lc is lowercase_filenames, see scrip below (tr would probably work as
well but old habits ...)
exiv2 is used rather than exiftool as exiv2 is compiled/faster
the rest should be rather obvious or I can explain if needed
script acts on all nef/jpg in cwd

ps: I never alter *originals* but always work on copies and then delete
unwanted originals/dups when I an satisfied. Nearing 100k *worked* images
with dt. (probably that many more with bibble before I found dt).
