How do I display line numbers in emacs (not in the mode line)?

Question

I know how to display line numbers (and columns) in the mode-line, but I'd like emacs to display the line numbers for all the lines on the left-hand side. I've seen this done in vim and other text editors. How do I do this for emacs?

Answer 1

M-x linum-mode (or global-linum-mode), and put (global-linum-mode t) in your ~/.emacs (or ~/.emacs.d/init.el) to enable it at startup.

Answer 2
