For changing the case in vi follow below step:

  1. Open file and go to command mode.
  2. type :%s/.*/\L&/ and for change to upper case type :%s/.*/\U&/
  3. Save the file.

I observe 2 different behaviors of vi that I cannot explain. 2 different machines, same distribution

On one machine when I underline some text with the mouse (not in append mode), vi turns to a VISUAL mode, and not in the other machine.
