Re: Premature close of the pipe

[McA]

Hi,

it is not a direct answer to your question and I don't know whether your code is just an excerpt from a bigger context. But if you just want to call rsync with grabbing the output synchronosly you could use the following:

my $rsync_base_cmd = "rsync -avm -L --exclude='S/' --include='*/' --in
+clude='*.cpp' " .
     "--include='*.hpp' --exclude='*'";
  
my $command = "$rsync_base_cmd ${login}:${remoteDirectory} $localDirec
+tory";
open my $fh, '-|', $command
    or confess("_copy_component Cannot perform rsync : $!");
my $output;
while(<$fh>) {
    $output .= $_;
}
close $fh or confess("rsync problem: $!");

Best regards

Hi McA,
thanks for your reply.

Well, I do not wish to necessarily grab the output from the pipe, the statement while(<$fh>) { $output .= $_; } was a trick to delay the premature death of the pipe.
I am using open3 because the remote server prints into the stderr a welcome message, which it is automatically forwarded into the client stdout using the common pipe mechanism, while I want to get rid of it.

Kind regards,
