Emacs - Autosave buffer every 5 seconds

Question

How can we configure emacs to automatically save the unsaved changes every 5 seconds? I want the save the buffer and not the temporary file generated with ~

Answer 1

In ~/.emacs file make following changes.

(require 'auto-save-buffers)
(run-with-idle-timer 5 t 'auto-save-buffers) 

Answer 2

change the auto-save-timeout's value affects the number of seconds idle time before auto-save.

using (setq auto-save-timeout 5) may solve your problem
