In emacs, as we open files, a lot of dired buffers get accumulated. I
personally find them a nuisance after a while specially during longer
emacs sessions. Killing them one by one using
C-X k would be quite
tedious. Fortunately there is better way to kill many buffers at a
For this we list all the buffers using
C-X C-b. The list opens in
a new buffer so we need to switch to this buffer using
C-x o. Now
we need to mark all the buffers that we wish to kill by typing
d. As we mark, a capital
D appears alongside the buffers'
names. After all buffers to be killed are marked, just press
all the buffers will get killed.
