- Stricly speaking, the output is only one "Bad command or file name".
- In fact, none of them are the output: one is the standard error
- and the other is just an echo. But, otherwise if you wish to consider
- the echo as output then I suppose you could always do
-
- REM blah
-
- Not mentioning the ultimate:
-
- CTTY NUL
-
- or even the more destructive
-
- CTTY CLOCK$
