    Hi All,
    In Perl6 for Windows, how can I get "qx" (or other) to
    send the output to the shell as its happens (not
    afterwards)?

      >ver
    Microsoft Windows [Version 6.1.7601]

      >perl6 -e "qx ( ver );"
    <nothing>


    (One of) my goal(s) is to watch "chkdsk" on the shell
    as it runs through its various stages.

    I might want the error code back.

    Many thanks,

So, you want to see the output as it happens, and the program doesn't 
need the output, it only needs the error code?

my $proc = run 'ls';
say $proc.exitcode ?? 'error' !! 'good' ;

I got that from the examples on https://docs.perl6.org/type/Proc#sub_run 
- even if documentation usually leaves you cold, that page has samples 
which look simple and useful.

Hi Yary,

Thank you!

I can't figure out

1) where it is getting its path from

2) why it looks so weird
