title: Get specific line from text file using just shell script
body: <p>I am trying to get a specific line from a text file.</p>
  
  <p>So far, online I have only seen stuff like sed, (I can only use the sh -not bash or sed or anything like that). I need to do this only using a basic shell script.</p>
  
  <pre><code>cat file | while read line
      do
         #do something
      done
  </code></pre>
  
  <p>I know how to iterate through lines, as shown above, but what if I just need to get the contents of a particular line</p>
