title: Delete All Characters After "." In Each Line
body: <p>I have a text file with about 2,000 lines of text and I want to remove a large portion of each line of text.</p>
  
  <p>The text is in this format: </p>
  
  <pre><code>Important Text that I care about. Stuff I want to delete
  </code></pre>
  
  <p>I am pretty new to vim and have been reading some manuals on vim commands but I am still unsure as to how to delete all of the text after the "." in each line. </p>
  
  <p>Can someone give me a quick command that would do this?</p>
  
  <p>Thanks</p>
