htaccess 301 redirect with pameters

I have some duplicated pages like:
link 1: http://www.domain.com/OldPage-par1aaa-par2bbb.html
link 2:
http://www.domain.com/NewPage-par1aaa-par2bbb.html


And I want in the htaccess file to permanently redirect (301) link1 to link2
someone can help me?

 

Redirect the whole thing using PHP

<?
Header( "HTTP/1.1 301 Moved Permanently" );
Header( "Location: http://www.new-url.com" );
?> 

PHP:

.htaccess

Redirect 301 /oldpage.html http://www.example.com/newpage.html

Code (markup):

 

I can´t, I have a lot of urls and par1/par 2 are paremeters so they change :
old links:
http://www.domain.com/OldPage-par1aaa-par2bbb.html
http://www.domain.com/OldPage-par1cccc.html
http://www.domain.com/OldPage-par1dd-par2eeee.html
..... and so on
new links:
http://www.domain.com/NewPage-par1aaa-par2bbb.html
http://www.domain.com/NewPage-par1cccc.html
http://www.domain.com/NewPage-par1dd-par2eeee.html
