dash after ampersant

Hi!

I'm new in these forums and more or less new with Unix. So... here is the question:

does anyone know where is redirected the output of a command when you put >&- after it?

Does it means any standard file descriptor?

Thanks!

It means close stdout.

From ksh93 man page

So... by closing stdout you are sending the output to nowhere. Is like that?

Thank you!
