This seems to have worked the best of all, after I turned off buffering for STDOUT/STDERR, with code such as this:
my ($ofh) = select(STDOUT); $| = 1; select($ofh);
$ofh = select(STDERR); $| = 1; select($ofh);
my ($out, $err);
run (
[ '/usr/sbin/pkgrm', 'VRTSvxvm' ],
'>', sub { $out .= $_[0]; print $_[0] },
'2>', sub { $err .= $_[0]; print $_[0] },
);
Now, if the program I was running demands that it connects to a pty before it will unbuffer STDOUT/STDERR properly, what could I do? I've tried the following, but it doesn't send any output to the screen:
use IPC::Run qw(run);
my ($out, $err);
run (
[ '/usr/sbin/pkgrm', 'VRTSvxvm' ],
'>', sub { $out .= $_[0]; print $_[0] },
'>', '>pty>',
'2>', sub { $err .= $_[0]; print $_[0] },
'2>', '>pty>'
);
