mod_rewrite question

How can I get mod_rewrite to use a wildcard in the url?

Hopefully somebody can tell me how to get this to work. I recently changed one of my OSCommerce sites to Ultimate SEO Urls and now I'm getting some duplicate pages as follows.

Problem URL: -c-0_240_274.html

I would like to rewrite these duplicate URL's so that the -c-0_240_274.html would be -c-240_274.html.

Hopefully somebody can tell me the syntax.

Thank you in advance!

It's not clear which part of the URL is fixed and which part is variable, nor is it clear how to identify the 'duplicate' part or how many/what type of characters each 'field' is expected to have. But this should demonstrate using constrained variable fields (rather than wildcards) generally:

RewriteRule ^(-[a-z]-)[0-9]+_([0-9]+_[0-9]+)\.html$ /$1$2.html [L]

$1 and $2 refer to the values matching the parenthesized sub-expressions in the requested URL.
