"man bash" and jump to the section on expansion.

(or ksh, or zsh, or any bourne-type shell)

No one expected you to know what that syntax was in all it's
gory details.

The answer was 3 things. It was the litteral answer to your
specific question. But it was also the the clue or hint that
such syntaxes even existed. And thirdly it was obviously an
example usage.

Pick up the ball and run with it.
Ask others for as much illumination as necessary along the way.
But at least try not to ask others to actually do all of your
thinking for you or to be your personal tutor.
(Asking a person to explain and spoon feed to you something that
you could already read for yourself, isn't that the very
definition of a tutor?)
