( #3333=superdoc: print w/replies, xml ) Need Help??

Thanks for the replies, the open is working properly on the background. I'm able to keep working while the $cmd is running.

The $reg_out is output to a text gadget. If you think the open cmd is the issue, how should I fix it? I want to run a CMD on the background, grep the output to be paste on a text gadget on the main process gui

This is the code of the fileevent, I'm closing the descriptor once the program is done

sub fill_text_widget { my $block = shift; my $numb = shift; my $widget = $Reg_r{$block}{$numb}{'Txt'}; my $out_rep = $Reg_r{$block}{$numb}{'OutP'}; if (eof($out_rep)) { $widget->fileevent($out_rep,"readable", undef); close $Reg_r{$block}{$numb}{'OutP'}; print "Got EOF\n" if ($DBG); $Reg_r{$block}{$numb}{'IsRun'} =0; &AddReRun($block, $numb); return; } $_ = <$out_rep>; $widget->insert('end', $_); $widget->yview('end'); }
