The Perl Cookbook from O'Reilly has nice examples, IMO.
The basic idea is really quite simple:
Iterative example:
for my $server (qw(huey duey louie)) {
do_lengthy_process($server);
}
sub do_lengthy_proces
{
... blah blah ...
}
Forking example:
for my $server (qw(huey duey louie)) {
defined(my $pid = fork) or die "Couldn't fork: $!";
unless ($pid) {
do_lengthy_process($server);
exit;
}
}
That's really all you need to do.
