.htaccess - Rewrite or Redirect url htacces -

i´m trying this, can´t it:

rewriterule ^(.*)pagina1(.*)$ $1pagina$2 [r=301,l] 

($2, because need pass parameters in url)

how can "redirect or rewrite" files: (pagina1.html, pagina2.html, pagina3.html,etc) pagina.html

i have work relative url, because want folders inside directory.

well, after 2 days trying, don´t know how can do...

with redirect *.html pagina.html

rewriterule ^([a-za-z0-9_-]+).html$ pagina.html [qsa]
