Dear perl monks,
I am struggling to keep my pipe open long enough so that the underlying command has the time to complete.
This is my code:
  state $rsync_base_cmd = "rsync -avm -L --exclude='S/' --include='*/'
+ --include='*.cpp' " .
     "--include='*.hpp' --exclude='*'";
  
  # perform the copy
  my $command = "$rsync_base_cmd ${login}:${remoteDirectory} $localDir
+ectory";
  #print("\n$command\n"); # for debugging
  #`$command`; 
  my $output = ""; 
  my $pid = open3(undef, my $pipe, undef, $command) 
    or confess("[_copy_component] Cannot perform rsync : $!");
    
  while(<$pipe>){ $output .= $_; } # wait it completes to process
  
  eval { close ($pipe); };
  
  waitpid($pid, 0);

Unfortunately the pipe terminates before the command is able to copy all the involved files. But if I print the output into the stdout, then the pipe will correctly finish and all the files will be copied.

Can you please tell me how to ensure the underlying command completes without having to print the output into the stdout?

Kind regards,
Superfox
