How can I hide the backup files that emacs creates?
emacs
Solution
You can either move them to their own folder with the following code:
;; Don't clutter up directories with files~
(setq backup-directory-alist `(("." . ,(expand-file-name
(concat dotfiles-dir "backups")))))
;; Don't clutter with #files either
(setq auto-save-file-name-transforms
`((".*" ,(expand-file-name (concat dotfiles-dir "backups")))))
Or you can remove them completely, like so:
(setq make-backup-files nil)
(setq auto-save-default nil)
Personally I would be wary of removing them as they can come in useful. Further discussion is here:

- http://www.emacswiki.org/emacs/AutoSave
I would recommend checking out the emacs-starter-kit it sorts out a load of issues that people have when coming to emacs, and is pretty heavily used.

Update:
There seems to be much confusion over how to use the functions. I'm going to have a little play around later but here is some more information. Note that `auto-save-file-name-transforms`:
lets you specify a series of regular expressions and replacements to transform the auto save file name [emacs-manual]
so it's not just as simple as adding in a folder name. That said it seems from a quick google search the following might just do what you all want:
;;; backup/autosave
(defvar backup-dir (expand-file-name "~/.emacs.d/backup/"))
(defvar autosave-dir (expand-file-name "~/.emacs.d/autosave/"))
(setq backup-directory-alist (list (cons ".*" backup-dir)))
(setq auto-save-list-file-prefix autosave-dir)
(setq auto-save-file-name-transforms `((".*" ,autosave-dir t)))

Problem
I just started using emacs after having used vi for a long time. :) One thing which is annoying me is that whenever I modify a file, save it and exit emacs, I see a backup file created in the same directory named `filename~` (if the file I edited was `filename`). Is there any way I can get rid of this? Or hide these files? It is very annoying to see tons of backup files when I do ls of the directory.
