This seems a bit of work to do strictly in Perl, but this should do what you want to do. However I do believe that davido's suggestion of the module is cleaner to work with as you're not doing the conversion of the hash to a sorted array, then to a string.

#!/usr/bin/perl/

use strict;

my %aa=(uno=>1, due=>2);
my %bb=(due=>2, uno=>1);

my ($aa,$bb,@aa,@bb);

**updated**
@aa=sort(%aa);
@bb=sort(%bb);

$aa = join("",@aa);
$bb = join("",@bb);

**updated

if ($aa eq $bb){
                print "Matches!\n";
                }
else{
     print "No match!\n";
     }

Update: As both samtregar and <a href="http://www.perlmonks.org/index.pl?node_id=56270>greenFox point out the original code blows up with the data they show in their nodes. However replacing the

@aa=%aa;
@bb=%bb;

$aa = join("",sort @aa);
$bb = join("", sort @bb);
[download]

with

@aa=sort(%aa);
@bb=sort(%bb);

$aa = join(" ",@aa);
$bb = join(" ",@bb);
[download]

I believe should do what I originally intended.

Sorting the hash, not the array, and leaving the space in should solve the problem found by the other monks.

• 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).
