if (my $pid = fork) { # parent ($pid is process id of child) parent_function(); } else { # child child_function(); exit; }
Feel free to read perldoc -f fork, and look at some examples online. This is not really advanced perl, but it requires some attention.

    Hello, Remember to check for a fork error after forking:
    if (my $pid = fork) { ## Parent } elsif ($pid == 0) { ## Child } else { ## Error, $pid is undefined }
