convert filenames in current directory to lowercase

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.
This is sample output - yours may be different.

for i in *; do mv "$i" "$(echo $i|tr A-Z a-z)"; done
