The simplest way I know. Show Sample Output
or, to process a single directory:
for f in *; do mv $f `echo $f |tr '[:upper:]' '[:lower:]'`; done

This will convert filenames from uppercase to lowercase. I find this useful after downloading images from my digital camera. This works for English, but other languages may need something slightly more complex like this:
for i in *; do mv "$i" "$(echo $i|tr [:upper:] [:lower:])"; done
Also, the quote marks aren't necessary if your filenames don't contain spaces.
easier way to recursively change files to lowercase using rename instead
Example of zsh globing, glob qualifier, and substitution: -Q state that the parameter will contain a glob qualifier. (**/)(*) is recursive (.) is our glob qualifier, with states the match is a file "." The first parameter $1, is then substituted with $2 but with lowercasing '(L)' ... a (U) would of course be from lower to upper.
Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
