title: Is there a command to output only part of a command result in Linux?
body: <p>My question is, when we type a command with <code>grep</code> in terminal we get output along with the title:</p>
  
  <p>For example:</p>
  
  <pre><code>lscpu | grep MHz
  </code></pre>
  
  <p>Will output:</p>
  
  <pre><code>CPU MHz:               1216.851
  </code></pre>
  
  <p>But what if I only want:</p>
  
  <pre><code>1216.851 
  </code></pre>
  
  <p>As the output? Is there any other command to perform this task?</p>
