Using the CPAN module Proc::Background, you should be able to write something like .. 
use Proc::Background;

my $proc = Proc::Background->new( $cmd );
$proc->wait; # wait for completion

Maybe a case of cracking a nut with a sledgehammer for this example, but it'd seem nice and clean, and to do what you need.

Hope that helps ..
