in reply to Strange (for me) behavior of Parallel::ForkManager

That's expected behavior---finish() is not supposed to return. But why would you want to pass in a code reference as a return code? None of the example code I've looked at does that.

In any case I what you need to do is call finish() within the loop:

while (<LIST>){ $manager->start and next; my @array = split( /\s+/, $_ ); # do child stuff $manager->finish; }

    It works , but how to make it go out of the loop?
      If you need to leave early, you can use "last". Otherwise it will just read to EOF and then quit.
        It does not quit loop after executing last iteration. This is the problem, need it to quit after last iteration but it does not. ...
      There's only one process that loops. It loops until it reaches the end of the file, at which point it continues after the loop.
