title: how to add/remove identical lines of text from multiple files via vim?
body: <p>i have hundreds of [mostly different] files in many different directories that all have an identical 5 lines of text in them that i need to frequently edit. example:</p>
  
  <pre><code>/home/blah.txt
  /home/hello/superman.txt
  /home/hello/dreams.txt
  /home/55/instruct.txt
  and so on...
  </code></pre>
  
  <p>the 5 lines of text are in sequence but begin at different locations in all of the .txt files. example:</p>
  
  <p>in /home/blah.txt:</p>
  
  <pre><code>line 400 this is line 1
  line 401 this is line 2
  line 402 this is line 3
  line 403 this is line 4
  line 404 this is line 5
  </code></pre>
  
  <p>/home/hello/superman.txt:</p>
  
  <pre><code>line 23 this is line 1
  line 24 this is line 2
  line 25 this is line 3
  line 26 this is line 4
  line 27 this is line 5
  </code></pre>
  
  <p>how can i find and replace those 5 lines of text in all of the .txt files?</p>
