in reply to Synchronous action

What is the underlying reason to copy at the same time?
If the purpose is to cut down on run time because it's a huge amount of data, use fork().
If it is a matter of concurrent synchronisation, you will need some kind of locking mechanism.

    Maybe I used wrong terminology. Not to make it complicated, I just wanted all robocopy to be started at teh same time from one source to multilple machines. PARALLEL. It saves time. If done in SERIAL, it takes a long time for the robocopy to finish. I shall research on FORK, meanwhile, I hope you get my idea, what am trying to do and using "synchronization" might have confused you all. oops.

      All you need is:

      for my $client ( @clients ) {
    ## Note: the '1' first parameter to system
    ## which means that the command will be executed asynchronously
    system 1, qq[ robocopy $srcmachine $client ]; 
}

        Can you explain what this does? Instead of calling robocopy at the same line, I would like to copy a function with two arguments, src and dest. meaning like this. 
        system 1, &startCopy( $srcMachine $client->[0]);

        But (in eclipse), its giving me a syntax error. Any suggestions on this?
