How can I hide the Tool-bar in Emacs persistently?

I have installed emacs23 on Linux Mint 8. I would like to hide the toolbar, and I can do it with Options > Show/Hide > Tool-bar. But the Tool-bar comes back next time I start emacs. How can I hide it persistently?

Solution 1:

Add the following to your init file (~/.emacs or _emacs or ~/.emacs.d/init.el):

(tool-bar-mode -1)

Solution 2:

Emacs has a nice built-in customization interface.

Select Options › Customize Emacs › Specific Option, start typing tool, then hit TAB to see the options starting with tool. Choose tool-bar-mode then. Toggle its value to switch it off, and press Save for future sessions.
