How to do a wildcard redirect?

[DanDeceuster]

Sorry if this is a dumb question, but I am not a programmer and my client's programmer is asking me how to set this up. Normally I do it in my cPanel, but they can't and need to write it in the .htaccess file.

The client's new website was posted at dev.site.com and of course their programmer put robots="index,follow" and so the site is completely indexed. They are launching it tomorrow at www.site.com.

I need a wildcard redirect that takes dev.site.com/anything and 301 redirects it to www.site.com/samething if that makes sense. Basically redirects every dev.site.com URL to www.site.com so we don't have duplicate indexation issues.

Can anyone tell me the code to do this that needs to go in the .htaccess file? I would just do it through cPanel but that's not an option, so any help is appreciated.
