zmv: move files based on a pattern

The default shell on macOS became zsh a while back, but I'm still learning the basics. I didn't know that zmv exists:

autoload -U zmv
zmv -nv 'ah Study (<->) 1.0 sec.wav' '$1.wav'

This would dry-run (-n) a rename of files that match the pattern on the left. E.g., a file like "ah Study 0083 1.0 sec.wav" becomes "0083.wav".

The documentation is towards the end of man zshcontrib.
