bash to list files of a certain type but only if condition is met
<p>I am trying to list specific file extension <code>.vcf</code> using <code>bash</code>.  The issue I am having is that there might be multiple <code>.vcf</code> in the directory, but the one that is needed only does not have a <code>_</code> in them rather it is just in the format <code>xxx.vcf</code> (name.vcf).  I am not sure how to do this but the below seems close.  Thank you :).</p>

<p><strong>Directory files</strong></p>

<pre><code>123.vcf
123_count.txt
123_variant_list.vcf
</code></pre>

<p><strong>bash</strong></p>

<pre><code>select file in $(cd /home/file/overall/stats;ls *.{vcf});do break;done
        echo $file
</code></pre>

<p><strong>desired output</strong></p>

<pre><code>123.vcf
</code></pre>
