title: Copy and paste content from one file to another file in vi
body: <p>I am working with two files, and I need to copy a few lines from one file and paste into another file. I know how to copy (yy) and paste (p) in the same file. But that doesn't work for different files. How is this done?</p>
  
  <p>Also, is there a way to cut-paste? I have tried googling, but most of the resources only talk about copy-paste.</p>
