  Do you mean wait until the child starts or wait until the child finishes?

  If the latter, take a look at 

    perldoc -tf wait
    perldoc -tf waitpid

  It's harder to know when a child process is fired up and ready for action.
  You have to arrange and manage some channel for communication, so that the
  child can say "okay, I'm ready" (signals, pipes, etc).
