redis-cli delete keys pattern not deleting records
<p>I have installed redis on my ubuntu server. I am traying to learn commands via <code>redis-cli</code>. I am seetnigs commands:</p>

<pre><code>127.0.0.1:6379&gt; SET book "read"
127.0.0.1:6379&gt; GET book 
127.0.0.1:6379&gt; DEL book 
</code></pre>

<p>And I can list multiple keys like this:</p>

<pre><code>127.0.0.1:6379&gt; KEYS "urn:products:*" 
</code></pre>

<p>These commands work fine but I want to delete multiple records with pattern.</p>

<pre><code>127.0.0.1:6379&gt; DEL "urn:products:*"
127.0.0.1:6379&gt; DEL KEYS "urn:products:*"
</code></pre>

<p>These commands not deleting records</p>
