title: Need to go back to prev commit in git,How?
body: <p>I have modified my source directory by deleting certain files and done a <code>commit</code>. And I did a <code>push origin master</code> to remote host, github.</p>
  
  <p>Now I came to know that I need those files for proper functioning. Now I need a way to go back my prev <code>commit</code> and then <code>push</code> to my remote host.</p>
  
  <p>Is it possible to do so? I'm very new to git, I'm confused with it.</p>
  
  <p>Thanks in advance. </p>
