What it does
Hides the output instead of sending it down the pipeline or displaying it. The Out-Null cmdlet sends its output to NULL, in effect, removing it from the pipeline and preventing the output from being displayed on screen. This only affects the standard output stream. Other output streams, like the Error stream are not affected. Exceptions will be displayed. This makes it easier to test your command for any errors.
