How would I redirect www to non www addresses?

I want to know what code I need to add this to my site's .htaccess file. Thanks.

 

Code:

 [COLOR=#00007F]RewriteEngine[/COLOR] [COLOR=#0000FF]On[/COLOR]
[COLOR=#00007F]RewriteCond[/COLOR] %{HTTP_HOST} ^example\.com$ [NC]
[COLOR=#00007F]RewriteRule[/COLOR] ^(.*)$ http://www.[COLOR=#00007F]example[/COLOR].com/$[COLOR=#FF0000]1[/COLOR] [R=[COLOR=#FF0000]301[/COLOR],L] 

 

Thank you.

 

Thank you too!
