redirecting urls of a certain pattern to another site

I have a website. The root directory of my site in cpanel was like this: www.example.com/b. But, I have changed my root directory to www.example.com/s. Now I want to redirect every url of the pattern like www.example.com/b, www/example.com/b/c/text/php etc. to this url: www.example.com/s. Is there any way to do this in cpanel?
