htaccess rule - redirect old URLs

Hello, I need new htaccess file for my company website. We changed the CMS from old to new one (Drupal7). Now we need to set htaccess file, with redirect 301 for all addresses (its basicly news pages, its about 6000 of them). We are albe to prepare script that will generate whole htacces file, but we need to know how should look the correct redirect (f.e. only 1 line). Example: old address: [login to view URL] new address: [login to view URL],-prawnik-odpowiada Important - the old addresses doesnt exist anymore (you can't view it etc.) Htaccess file can't affect the website. This is very urgent.
