Maybe not out-of-the-box, but it certainly can be installed from CPAN, check the ppm command

Nope. Check the Tee CPAN page for syntax: Tee @ CPAN

Try this:
Code:
#!/usr/bin/perl

use strict;
use warnings;

my @arr;

print "Output from screen:\n";

open(FROM, "ls |") or die "Could not open pipe: $!\n";

while (<FROM>) {
chomp;
print "$_\n";
push @arr, $_;
}

close(FROM);

print "Output from array:\n";

 foreach (@arr) {
 chomp;
 print "$_\n";
 }

CPAN::Meta::YAML(3pm)					User Contributed Perl Documentation				     CPAN::Meta::YAML(3pm)

NAME
CPAN::Meta::YAML - Read and write a subset of YAML for CPAN Meta files VERSION
version 0.008 SYNOPSIS
use CPAN::Meta::YAML; # reading a META file open $fh, "<:utf8", "META.yml"; $yaml_text = do { local $/; <$fh> }; $yaml = CPAN::Meta::YAML->read_string($yaml_text) or die CPAN::Meta::YAML->errstr; # finding the metadata $meta = $yaml->[0]; # writing a META file $yaml_text = $yaml->write_string or die CPAN::Meta::YAML->errstr; open $fh, ">:utf8", "META.yml"; print $fh $yaml_text; DESCRIPTION
This module implements a subset of the YAML specification for use in reading and writing CPAN metadata files like META.yml and MYMETA.yml. It should not be used for any other general YAML parsing or generation task. NOTE: META.yml (and MYMETA.yml) files should be UTF-8 encoded. Users are responsible for proper encoding and decoding. In particular, the "read" and "write" methods do not support UTF-8 and should not be used. SUPPORT
This module is currently derived from YAML::Tiny by Adam Kennedy. If there are bugs in how it parses a particular META.yml file, please file a bug report in the YAML::Tiny bugtracker: http://rt.cpan.org/NoAuth/ReportBug.html?Queue=YAML-Tiny <http://rt.cpan.org/NoAuth/ReportBug.html?Queue=YAML-Tiny> SEE ALSO
YAML::Tiny, YAML, YAML::XS SUPPORT
