how to route uri with dash in codeigniter

Question

I am trying to control my routing in codeigniter.

I have my url which is: www.domain.com/all-artists. If I am going to accept the dash controller, I need to configure the route.php below:

 <?php $route['all-artists']  =  "all_artists";

The above routing works. Now, I want to visit this url: www.domain.com/all-artists/x

The "x" method from the uri above is dynamic, which means that I can change it from a-z. However, this url returns an error display.

Do you know how to route these urls that can accept even segment(1) with dashed and contains dynamic methods?

I've used routing for how many years but this seems new to me... Why downvote? — smz
because the answer is in the CI manual...under routing...really not hard to find or look up — charlietfl
If the answer is in the manual, I ask you this question.Do you know the answer if it's in the manual? — smz
that's really irrelevant what I know...asking here should not be you first line of research effort...did you even look? Most people would start there when a method isn't working as expected. And the docs are easy to navigate — charlietfl

I got this routing:

 <?php //route.php
 $route['all-artists']          =  "all_artists";
 $route['all-artists/(:any)']  =  "all_artists/function_name/$1";
 ?>

This routing will accept both www.domain.com/all-artists and www.domain.com/all-artists/x
