The core module IO::Pipe is easy to use and works on both Linux and MS Windows. However, it doesn't handle STDERR.

The reader and writer methods expect a program to run and a list of arguments. The shell is not used.

#!perl
use strict;
use warnings;
use IO::Pipe;

my $pipe = IO::Pipe->new();
$pipe->reader(qw(ls -l));
while(<$pipe>) {
    ...
}
