How to quit one file and simultaneously open another file in vim?

Question

I am currently editing one file and, after finishing its edit, I want to close the current file and at the same time (i.e., without closing Vim) open another file for editing.

How it can be achieved?

Answer 1

I don't think this can be done using a single command. You'll have to use a combination of commands:

1. As statox suggested, delete the current buffer and open a new one:

   :bd | e filename
   

2. Or rename the current file and edit it:

   :file filename | e
   

Use :w | bd | e filename or :w | file filename | e to save the current file and start on a new one.

You can, of course, use maps or custom commands to simplify this:

:command -nargs=+ WE w | bd | e <args>

Then do:

:WE new-filename
