perl -e 'map { rename($_, lc($_)) unless (-f lc($_)) } <*[A-Z]*>'

Much more efficient:  Only invokes perl once (instead of once per file),
and only tries to rename files which actually have a capital letter in
their name.

(mind you, talking about efficiency when we're invoking perl to rename
some freakin' files offends my sensibilities just a bit :-)
