title: git log show one commit id only
body: <p>I need some help. It is possible to only show one commit id? Since git log -3 show the log from 1 - 3, I just want to show only 3. What possible command will match for it?</p>
  
  <p>I use the command</p>
  
  <pre><code>       git log -3 --pretty=format:"%h"
  </code></pre>
  
  <p>the result is</p>
  
  <pre><code>       ffbef87
         cf0e073
         1c76c5d
  </code></pre>
  
  <p>I only want to display the <strong>1c76c5d</strong> only.</p>
