Well guys i post the solution for this isuee

When i think in execute multiple files without wait i say, ok, i need use childs

Anyway the solution come more simple, like this:

#!/usr/bin/perl

use strict;
use warnings;

for my $a ( 1..10 ) {
      print "Exec: $a\n";
      # Here I want execute and continue without
      # wait the status
      system "perl -e exec('sleep.pl')" ;
}

print "finish";
exit;

It's delegate the process to other instance of perl and exist when finish, i check in the system's process table and works ok!!

system(1, @args) can be but i'm not test

Thk to all for your help
