No, fork doesn't work that way. fork() simply makes a second process which
is a duplicate of the first. In order to run a different program, you need
to call exec() after the fork:
defined(my $pid = fork) or die "Couldn't fork: $!";
unless ($pid) {
exec "perl anotherscript.pl" or die "Couldn't exec: $!";
}
... first process continues here ...
See:
perldoc -f fork
perldoc -f exec
perldoc -f wait
perldoc perlipc
You may want to take additional measures to disassociate the second process
from the controlling terminal and process group. See:
perldoc -q daemon
