Question

:q only closes the current window. If you are using tabs or split windows, you need to do :q for all of them. Also, plugins like NERDTree and MiniBufExpl have their own windows, which need to be closed individually.

Is there a command to quit all these open windows and quit Vim in a single stroke? However, if there is some buffer or window with unsaved changes, I should be asked to save it or not. Any command to achieve this?

I hope this is not a strange request, because this is how most non-Vim editors with tab or splits work.

Answer 1

You can quit all loaded and open buffers, splits and tabs with:

:qa

If you want to quit without saving:

:qa!

You could assign a mapping to do this with a single stroke, this assigns the comma to quit everything without prompting to save:

nnoremap , :qa!<CR>

:wqall writes before closing, that might be useful.

Type :he :qa in vim for more info
