Hi,
I usually run this piece code of mine under console shell as follows: 
$ perl mycode.pl filename > ~/MyPerl/result_ans/filename.out

Now, I want to run this command again but within a Perl code, using Shell module. Here is the snippet of how I do it: 
perl("mycode.pl filename > ~/MyPerl/result_ans/filename.out");

[download]
But this doesn't work. Why?
The full context of what I am trying to do is shown in the following complete script: 
use Shell;
use Proc::Queue size=>5, qw(run_back);

my @list = glob("*.fasta");


foreach my $list (@list) {
     run_back { run_code($list) } 
}

sub run_code {

    my $fname = shift;
    my $base = ( split( /\./, $fname ) )[0];
    perl("mycode.pl $base > ~/MyPerl/result_ans/$base.out");

    # Tried this too, but still doesn't work
    # system("perl mycode.pl $base > ~/MyPerl/result_ans/$base.out");

    return ;
}

1 while wait != -1;

What I am trying to do above is to run the script in paralel process across the globbed files.
Can anybody advice how can I go about this correctly?

Update: Parallel::ForkManager version of the above code also doesn't work. 
use Parallel::ForkManager;
use Shell;

my @list = glob("*.fasta");

my $pm = new Parallel::ForkManager(10);

foreach my $list (@list) {

    my $pid = $pm->start and next;
    my $base = ( split( /\./, $list) )[0];
    system("perl mycode.pl $base > ~/MyPerl/result_ans/$base.out");

    $pm->finish; # Terminates the child process

}
