Well the code under the box telling you where to download it (at least
in the pdf version of the book, too lazy to go upstairs to look at the
physical version) is a complete ruby program,  either download it or
enter it into a file they suggest intro5.rb,

And then just run it with:

    ruby intro5.rb

Alternatively you can paste the text into irb.

puts say_goodnight("John boy")

is the same as

puts(say_goodnight("John boy"))

and invokes the puts function passing the result returned by invoking
say_goodnight("John boy")

puts (p 575) is actually a method defined in the Kernel module which
is available for all instances of subclasses of Object which includes
Kernel.

But at this stage of the book, I believe that the author is just
trying to give you the 'flavor' of Ruby, It might be better to just
read the material, without trying to understand things too deeply.
The picture will get clearer as you progress through the book.
