Best way is with ports/misc/mmv:
mmv "?*" "=l1=2"
If you use zsh, you can use the zmv function to do the same thing:
autoload -U zmv
zmv '([A-Z])(*)' '${(L)1}$2'
Both of the above will detect filename collisions and tell you what
won't work. If you know there aren't any collisions, you could do this
(zsh again):
for i in [A-Z]* ; do
mv $i ${i[1]:l}${i[2,-1]}
done
