Chaks has asked for the wisdom of the Perl Monks concerning the following question:

I am using a system command in Perl to execute java. I have formed an array @args that have different options to execute a jar file. Something like below: 
$args[0] = $rootpath."/jre/bin/java";
$args[1] = " -jar \"".$rootpath."/temp/abc.jar\"";
$args[2] = " INP=\"".$inputfilename."\"";
$args[3] = " OUT=\"".$outputfilename."\"";
system(@args);

[download]
This gives a popup window when executed which I want to suppress and want it to run in background. I want this to be suppressed in Linux also. I tried using tild but it didn't helped as below. 
my $command = "@args";
$output = `$command`;

Please help in figuring this out. I have similar post on stackoverflow http://stackoverflow.com/questions/30885201/suppress-windows-cmd-for-system-command-in-perl?noredirect=1#comment49841195_30885201

    Try: system( 1, qq[start /b your command and args here] );

      Ah, the days of fiddling with start. Why the F*** does Micr$oft name things with overloaded words? I think it's a plan to avoid any possible bad words in every language in the world. Windows. Surface. Access. Excel (well, at least they changed the spelling). Outlook. Office. Explorer. Natural. Publisher. Vista. Visual <anything>. Xbox.

      Thanks BrowserUk. I tried using that but still I see the cmd window popup.

        Hm. I cannot reproduce the problem on my machine. Neither the original problem or when using start.

        Are you running the perl script you are using from a command line; or double clicking it in the explorer?

      I tried using that but it did not help. Still I am getting the pop-up when system command is called. Also in my application I have some restriction to include new module like Win32. So I am looking for some other ways to remove the pop-up. If it doesn't help and including Win32 is the only way and I have the working model for it then I can take on this further.

        No wonder Chaks, you left out critical details twice, took until this to reveal you're calling perl from c++

        So here is what you do, in c++ program, use SetChildShowWindow(0), so that when the c++ program starts programs there is no popup
