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";
 }

PARSE_STR(3)								 1							      PARSE_STR(3)

parse_str - Parses the string into variables

SYNOPSIS
void parse_str (string $str, [array &$arr]) DESCRIPTION
Parses $str as if it were the query string passed via a URL and sets variables in the current scope. Note To get the current QUERY_STRING, you may use the variable $_SERVER['QUERY_STRING']. Also, you may want to read the section on vari- ables from external sources. Note The magic_quotes_gpc setting affects the output of this function, as parse_str(3) uses the same mechanism that PHP uses to populate the $_GET, $_POST, etc. variables. PARAMETERS
o $str - The input string. o $arr - If the second parameter $arr is present, variables are stored in this variable as array elements instead. RETURN VALUES
No value is returned. EXAMPLES
Example #1 Using parse_str(3) <?php $str = "first=value&arr[]=foo+bar&arr[]=baz"; parse_str($str); echo $first; // value echo $arr[0]; // foo bar echo $arr[1]; // baz parse_str($str, $output); echo $output['first']; // value echo $output['arr'][0]; // foo bar echo $output['arr'][1]; // baz ?> SEE ALSO
