@r1w1s1 This is the way. But why nvi instead of vim or neovim?
It is interesting as a teacher, when teaching people with only ipad or windows experience. After my linux class, about 10%-20% of the class come to me and say they had no idea that it was possible to become so fast at accomplishing things on the computer. The terminal opened their eyes to a completely new way of using computers. They go on to become great technologists.
