Perhaps the following will be helpful:
use strict;
use warnings;
use Cwd;
use JSON;
my %hash;
my $currDir = Cwd::cwd();
push @{ $hash{$currDir} }, { name => $_, size => ( stat($_) )[7] } for
+ <*>;
my $j = encode_json \%hash;
print $j;
Sample output:
{"/home/user/programming/Perl/tmp":[{"name":"File1.txt","size":63},{"n
+ame":"File2.txt","size":55},{"name":"temp5.pl","size":196},{"name":"t
+est.pl","size":197}]}
When run, it gets the current dir, uses it as the hash key whose value is a reference to an array of (file and filesize) hashes. That hash is later json encoded. Substitute your own path in $currDir, as needed.

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).
