in reply to Execute command, show realtime output and get exit code

...and $? is zero, so I can't get a return code.

close waits for the subprocess and sets $?:

my $pid = open X, '-|', 'echo foo; exit 42' or die $!; my $out = <X>; my $ok = close X; print STDERR "out=$out"; printf STDERR "\$?=%s\n", $? >> 8 unless $ok; __END__ out=foo $?=42

See close for details.
