title: unix command to read line from a file by passing line number
body: <p>I am looking for a unix command to get a single line by passing line number to a big file (with around 5 million records). For example to get 10th line, I want to do something like </p>
  
  <pre><code>command file-name 10
  </code></pre>
  
  <p>Is there any such command available? We can do this by looping through each record but that will be time consuming process.</p>
