> How do you copy-paste file or folder paths between terminal and Finder? Anyone?

Drag the file or folder from Finder to your terminal to copy the path.

To open a file or folder in Finder from your terminal simply run `open <path>`.

The open command also works with any url whose protocol has a registered handler, like slack:// or https://. With a path the file:// protocol is assumed, and Finder is its handler. Moreover since this is a unix system with good documentation, `man open` will help you with more advanced usage.
