in thread Determine if a program in a different terminal has ended

using a sleep() would be useless

I just put the sleep in there for testing purposes, i.e. to emulate a script doing something that takes time... (if the script doesn't do anything, the terminal would of course also close immediately)

I still wonder what's happening in your case.  The "normal" thing for a terminal would be to wait until the command it runs has finished...

What happens on your system when you try

for (1..3) { system("gnome-terminal -e 'sleep 2'"); }

    For demonstration, try this... I'm having trouble explaining my situation hehehehe
    # myscript.pl # # script must be run in a terminal # use Gtk2 '-init'; my $window = Gtk2::Window->new(); $window->signal_connect( destroy => sub { exit } ); my $button = Gtk2::Button->new("click me to close"); $button->signal_connect('clicked'=> sub { exit } ); $window->add($button); $window->show_all(); Gtk2->main;

    next is the main code
    # main.pl # my $k = 0; while($k < 3){ system("gnome-terminal -e 'perl myscript.pl'"); $k++; }

    if i ran main.pl it call the script 3x then ends... yet the first myscript.pl has not yet finished running... it waits for you to press the button... what i wanted to do is... open the 1st myscript.pl then wait for somebody to press it... then if somebody presses it, another myscript.pl would run again.. then so on..
    Mabuhay Civil Engineers! :D

      Works for me as expected, i.e. the program waits util I click the close button in your GUI, then the next instance (of terminal and GUI) is started...   (in this particular case, a terminal wouldn't even be required)

      Do you in fact get three instances of the GUI running at the same time?

        Is one of you running on Windows, and one on *nix?
