Delete .DS_STORE files in current folder and all subfolders from command line on Mac

find can do that. Just add -delete:

find . -name ".DS_Store" -delete

find . -name ".DS_Store" -print -delete

This will delete all the files named .DS_Store in the current path while also displaying their relative paths

You can also use extended globbing (**):

rm -v **/.DS_Store

in zsh, bash 4 and similar shells (if not enabled, activate by: shopt -s globstar).
