Maybe this will shed some light:
#!/usr/bin/perl
use warnings;
use strict;
opendir(DIR, '.');
my @files = grep !/^\.{1,2}$/, readdir DIR; #no . or ..
@files = grep /08|09/, @files; #only 08 09 files
closedir DIR;
print "@files\n";
my @commands;
foreach my $file (@files){
my $string = `ls -l|grep $file`;
push @commands, [$file, $string]; # push arrayref
}
print join "\n", @commands,"\n";
foreach my $arrayref( @commands){
print $arrayref->[0]. "\t=\t". $arrayref->[1],"\n";
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
