<p>You can use this once every second to generate a unique random "UUID". This is because <code>srand()</code> uses the system time in seconds since epoch as argument if there is no argument given.</p>

<pre><code>for n in `seq 100` do awk 'BEGIN{for(srand();j++&lt;32;printf(j~"^9|13|17|21"?"-":E)"%c",x+(x&gt;10?87:48))x=rand()*16}'; sleep 1; done

<p>I think the awk part is rather elegant.</p>

<pre><code>BEGIN{
    srand()
    for(;j++&lt;32;) {
        x=rand()*16
        x+=(x&gt;10?87:48)
        printf "%c", x
        if(j~"^8|12|16|20")printf "-"
    }

</code></pre>

<p>If you want to use it more often than once every second you can call it in bash like this. Note that the awk part is changed too.</p>

<pre><code>echo `awk 'BEGIN{for(srand('$RANDOM');j++&lt;32;printf(j~"^9|13|17|21"?"-":E)"%c",x+(x&gt;10?87:48))x=rand()*16}'`

<h1>I need a UUID. Your job is to generate one.</h1>

<p>The canonical UUID (Universally Unique IDentifier) is a 32 digit hexadecimal number with hyphens inserted in certain points.The program should output 32 hex digits (128 bits), in the form of <code>xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx</code> (<code>8-4-4-4-12</code> digits), where <code>x</code> is a random hexadecimal number. Assuming that your language's PRNG is perfect, all valid outputs must have the same probability of being generated.</p>

<h2>TL;DR</h2>

<p>Generate 32 random hexadecimal digits in the  form <code>8-4-4-4-12</code> digits. Shortest code wins. </p>

<p>EDIT: Must be hexadecimal. Always generating decimal only is invalid.
EDIT 2: No built-ins. These aren't GUIDs, just generic hex digits.</p>

<hr>

<h2>Example output:</h2>

<pre><code>ab13901d-5e93-1c7d-49c7-f1d67ef09198
7f7314ca-3504-3860-236b-cface7891277

<p>Input, and <a href="http://meta.codegolf.stackexchange.com/questions/1061/loopholes-that-are-forbidden-by-default">standard loopholes</a> are disallowed.</p>
