You could do it without the module with a piped open: sub run_cmd { my $cmd = shift; open my $fh, '-|', "$cmd 2>&1" or die "open: $!"; print while<$fh>; close $fh; return $?>> 8; }Interesting. I did not realise that open '-|' with a single argument will pass this as a small shell program. But it does:
It _has_ to use the shell because of the "2>&1" redirection of stderr won't work without the shell doing the redirection.
