Mac: Change all filenames in directory to lowercase using Terminal

Recently, I needed to change 210 image filenames to be lowercase. I needed a quick way to do this other than one-by-one. Found this handy little script.

Open terminal, navigate to the directory with your images and paste this in the terminal window:

for f in *; do mv "$f" "$f.tmp"; mv "$f.tmp" "`echo $f | tr "[:upper:]" "[:lower:]"`"; done

Thanks to this solution on Stack Overflow –
