hi,

to make a simple daemon just de-attach the called script with this peace of code:

die "Cannot continue :$!" unless(defined(my $kid = fork()));
unless ($kid){
  system("my scheduler");
  exit;
}

and now when you demonize your script then you can with a simple while loop schedule all scripts set in some dir like:

in my scheduler :
-----------------

while(1){
  # predefined diractory
  opendir(DIR,"some dir") || die "$!";
  foreach my $sc (readdir(DIR)){
     next if ($sc=~/\./g);
     system($sc);
  }
  sleep 3600; # of whatever time you need
}

and that is more-or-less what you need to set up your first crone-like application. (just remember to set the absolute path with readdir -> it just captures the names of scripts in opened folder). of course don't forget to chmod to 555 to all files in defined dir (either through perl or manually).

good luck !
