List Buffers: ibuffer
ibuffer is a improved version of
list-buffers. It colors the files by type.
ibuffer as default, put the following in your init file:
(defalias 'list-buffers 'ibuffer) ; make ibuffer default
Select the code and call

Batch Operation on Buffers

- Save all unsaved files
- Close all files of a given dir
- Close all Java files
describe-mode to see a full list of ibuffer commands.

|【* u】||Mark unsaved|
|【S】||Save marked buffer|
|【D】||Close marked buffers|
ibuffer, the key sequence 【* u S D】 will save all unsaved files and close them. This is particularly useful after you've done a find replace on hundreds of files with
dired-do-query-replace-regexp. 〔►see Emacs: Find Replace Text in Directory〕
