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
Quote:
<&digit- The file descriptor given by digit is moved to standard input. Similarly for the
standard output using >&digit-.

<&- The standard input is closed. Similarly for the standard output using >&-.

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

Thank you!
