Actually you are right. I didn't real explained myself. I do want to terminate the threads childs and do some processing afterward (writing to a DB) , and then exit the child (fork) , and then exit the father. I got some answers here - and it really really helped, so thank you for that. I used the shared variable, and manaaged to kill all threads how I wanted. the problem now is that , if I dont kill the thread - I just get a hang , and nothing happens . I just don't know how to signal the sleep that all threads ended succesfully (and I want to join them). here is what I got so far : 
$SIG{USR1} = sub {shutdown = 1;};

foreach my $functions_name (@func_arr){
#Start new thread
      my $t = threads->create (sub{
         &$functions_name(@parameters);
         $SIG{KILL} = sub {
            print "\ngot to thread killer\n\n";
            threads->exit();
         };
         print "\ngot to end of thread\n\n";
         #$shutdown = 1;
      });
      push(@threads,$t);
   }
   
   sleep until $shutdown;
   
   if (my @remain = threads->list(threads::running)) {
      foreach (@remain) {
         if ($_ != $$){
            $_->kill('KILL')->detach;
         }
      }
      $shutdown = 0;
      testProcess::prc_kill_handler();
   }
   
   print "All threads exited normally.";

   my $index=0;
   foreach my $thread (@threads) #wait for all threads untill the end 
+and insert results to hash
   {
      $hash_results{$index}=$thread->join;
      $index++;
   }  
   
   return %hash_results;

Again ,this code actually works good when sending USR1 signal , but it doesn't when I'm not sending any signal , it just reaches to : 
print "\ngot to end of thread\n\n";

and then nothing happens. how can I handle that ? thanks again guys ! sorry if I'm not so clear again...
