whats wrong with this rewrite :S

I have a folder named as "ali_veli"

I want to use it as "ali-ve-veli" , so;
this works

RewriteRule ^ali-ve-veli/ ali_veli/ 

Code (markup):

I also want to redirect any request on old folder name and any sub file/folder requests to new folder name.


but this does no work

RewriteRule ^ali-ve-veli/ ali_veli/ 
RedirectMatch 301 ali_veli(.*) ali-ve-veli/$1

Code (markup):

any ideas ?
