How to configure GNU Emacs to write UNIX or DOS formatted files by default?

Question

I\'ve had these functions in my .emacs.el file for years:

(defun dos2unix ()
  \"Convert a DOS formatted text buffer to UNIX format\"
  (interac         


        

Answer 1

I've got a bunch of these in my .emacs:

(setq-default buffer-file-coding-system 'utf-8-unix)
(setq-default default-buffer-file-coding-system 'utf-8-unix)
(set-default-coding-systems 'utf-8-unix)
(prefer-coding-system 'utf-8-unix)

I don't know which is right, I am just superstitious.
