title: How to reset profile file on linux?
body: <p>I have got an Amazon EC2 instance. I edited <code>etc/profile</code>, which has resulted in something terrible. Now, I am not able to connect to the instance from <code>Filezilla</code>. I am able to connect through <code>putty</code> but the terminal opens with lot of text. I am definitely sure this is all because of something accidental changes that I created in <code>profile</code>.</p>
  
  <p>Is there any way I can reset <code>etc/profile</code> to its earlier version?</p>
