title: How to delete content of a log file from linux terminal?
body: <p>I have a log file on server called <code>writelog</code> which is about <code>2GB</code>.</p>
  
  <p>I want to delete first <code>100,000</code> lines from the file. I could open the file and delete those lines but because of the file size it takes me forever to download it.</p>
  
  <p>So, is it possible to do this from Linux terminal? If yes how?</p>
