To toggle globally, Alt+x global-linum-mode.

To set it permanetnly, put this in your emacs init:

(global-linum-mode 1) ; always show line numbers

How to set line number to start at 0?

If you want line number to start at 0, put this in your emacs init file:

(require 'linum)
(setq linum-format
      (lambda (line)
        (propertize (number-to-string (1- line)) 'face 'linum)))

Setting line number to start at 0 is useful because some editors do that. See: bug#4274.

linum-mode is written by Markus Triska. Thanks Markus.
