How to delete multiple buffers in Vim?

Question

Assuming I have multiple files opened as buffers in Vim. The files have *.cpp, *.h and some are *.xml. I want to close all the XML files w

Answer 1

Very simply: use the :bd[elete] command. For example, :bd[elete] buf#1 buf#5 buf#3 will delete the buffers 1, 3, and 5.

Answer 2

TAB will only autocomplete one file for you as of Vim 7.4.282
use <c-a> to autocomplete all files.

You can just use:

bd filetype

then just use <c-a> to facilitate the completion of all open files of specified filetype.

for example, you have 1.xml, 2.xml, 3.xml, and 4.xml, you can do:

bd xml

then press <c-a>

vim will autocomplete for you as follow:

bd 1.xml 2.xml 3.xml 4.xml

you can just press enter to complete the command.

if you have made changes in one of the files mentioned above, do remember to do:

bd! xml
