'> /dev/null 2>&1' equivalent?

[Michael G Schwern]

MakeMaker defines a macro to tack onto the end of a shell command to make it
silent. DEV_NULL.

On Unix its '> /dev/null 2>&1'.
Windows defines it as '> NUL'.

MacOS Classic doesn't have a definition and that causes problems. It means
more code that really has to be is overriden in MM_MacOS.pm to strip out
$(DEV_NULL) calls.

Is there something MakeMaker can stick on the end of a command in the MPW
shell (I think its the MPW shell that MM_MacOS is typically run with) to
supress its output?

Yeah, it is also noted in test.pl:runperl():

$runperl .= " \xB3 Dev:Null" if !$args{stderr} && $is_macos;

By default, stderr and stdout are both returned together. \xB3 ("„") will
redirect STDERR. Dev:Null is the null device.

Is there a way to redirect both STDERR and STDOUT?

Keep your stick on the ice.

Oh right, you want both. That's what I get for answering late at night.

"\xB7 Dev:Null"

\xB7 (capital sigma, "…") specifies both "output" and "diagnostic"
(STDOUT/STDERR) at the same time.
