In below code I am iterating my hash and checking if value of res.ldlibrarypath(key) equals to content of $target, Actually I want to substitute some of the content of the value so I am doing substitution, But can any one tell me how can I update my hash after that substitution? 
    for my $hashref($HR_wnt,$HR_unx,$HR_component)
    {
        for my $id (keys %$hashref)
        {
            if ($id eq 'res.ldlibrarypath')
            {
                if ($$hashref{$id} =~ /=\//)
                {
                $$hashref{$id}=~ s/\/opt\/app\/$target.*?://;

                }
            }
        }
    }
