Convert Filenames Recursively to Lower Case
Add a commentcheat-sheet articles are about code snippets that I need every once in a while, and which I constantly forget about.
Use zmv to recursively convert the names of all files and (sub-) directories
within the current directory to lower case:
autoload zmv
zmv '(**/)(*)' '$1${2:l}'
If you want to convert to upper case instead of lower case, use :u instead
of :l.
