Vim: Close All Buffers But This One

Question

How can I close all buffers in Vim except the one I am currently editing?

Answer 1

I do this

:w | %bd | e#

My favorite if I just want my current buffer open and close all others.

How it works: first write current buffer's changes, then close all open buffers, then reopen the buffer I was currently on. In Vim, the | chains the execution of commands together. If your buffer is up to date the above can be shortened to :%bd | e#
