How to extract one integer value from multiple integers present
<p>I have the following string, output of df command.</p>

<pre><code>$ df |grep data
/dev/block/dm-1  11066964 2103848   8946732  20% /data
</code></pre>

<p>I want to extract value </p>

<pre><code>8946732
</code></pre>

<p>using java regex, I have tried </p>

<pre><code>(.*?\s{3}\d+.\d+)
</code></pre>

<p>but it is not working fine.</p>
