It may have to do with the fact that you can't write to ls...the following
worked for me
use IPC::Open2;
use strict;

The Perl Cookbook recipie 16.8 says
use the standard IPC::Open2 module:
use IPC::Open2;
open2(*README, *WRITEME, $program);
print WRITEME "Here's your input\n";
$output = ;
close(WRITEME);
close(README);
However, it warns that there could be problems if the other program buffers
input or output
