Section titled “Why it works”The shell splits a command line into words on whitespace, meaning an unquoted name with spaces arrives as several separate arguments. Quoting the whole path (or escaping each space, or tab completing) passes it as one. The leading dashes also need the ./ prefix so the name is not read as an option.
