See zmv in the Functions/Misc directory of 3.1.9 (this version is needed
for it to work).
zmv '(**/)(*[ A-Z]*)' '${1}${(L)2/ /_}'
works on a simple test case (use the option -n just to test what it would
do). Each parenthesis maps to a positional parameter; (**/) is a special
case and is the only sort of multi-directory pattern that works. Looks
like zmv needs the option to ignore files whose names didn't change (it's a
pain having to make the LH pattern so specific). I'd appreciate any
feedback about zmv.
