One of the clues is the exitcode=1, there is an error coming back.
I think there are two issues which I didn't realize until now
1. DOS command "dir" is a cmd.exe built-in, not its own executable
2. Raku (perl6) "run" takes a list of arguments, not a space-separated
command-line
Let's try these (I still don't have my windows machine with me)
perl6 -e "my $proc=run qw[cmd /c dir]; say 'Exit code=', $proc.exitcode;"
C:\NtUtil>perl6 -e "my $proc=run qw[cmd /c dir]; say 'Exit code=',
$proc.exitcod
e;"

If you want to interpolate variables and still have a space-separated
list, use qqw instead of qw. Unix-y example:
perl6 -e 'my $dir="/tmp", my $proc=run qqw[ls $dir]; say $proc.exitcode'
C:\NtUtil>perl6 -e 'my $dir="/tmp", my $proc=run qqw[ls $dir]; say
$proc.exitcod
e'
===SORRY!=== Error while compiling -e
Unable to parse expression in single quotes; couldn't find final "'"
(correspond
ing starter was at line 1)
at -e:1
------> 'my<HERE><EOL>
expecting any of:
single quotes
statement list
term
... and now I remember Raku has a "shell" routine that's like "run" but
it also creates a shell.
perl6 -e "my $proc=shell 'dir'; say 'Exit code=', $proc.exitcode;"
C:\NtUtil>perl6 -e "my $proc=shell 'dir'; say 'Exit code=', $proc.exitcode;"
