htacess help needed, I gave up!

[Muhammad Mustafa]

I need to change the default .htaccess mod_rewrite as follow

RewriteRule ^([0-9]+)\-([a-zA-Z0-9-]*)(.*)$ /category.php?id_category=$1 [QSA,L,E]


mysite.com/id-category
to
mysite.com/category/


I changed link.php and link structre working OK allover my store, but I had to manual rewrite each single category in .htaccess, any solution to the above RewriteRule to achieve the target??
