Just enough vi to open a file, edit it, and quit

September 19, 2018

vi is something I use rarely, usually when I don’t have access to a GUI text editor. For those times, here’s just enough to do what I need:

1. vi <file> to open the file
2. Press i for “INSERT” mode
3. Make changes
4. Press esc then enter :x to quit and save changes. To quit without saving changes enter :q!
