  I've installed the **Retour** plugin and have been able to get most of my redirects working, but have now run into a situation where the old site had multi-level category hierarchy eg: /category/category-slug/sub-category-slug url structure and the new site only has a single level eg: /news/category/category-slug
  
  How can I create a Regex to grab the last segment off the url, if there is more than one level of category, to use for my redirect ?
  
  Looks like if there was only one level then the following would do:
  
  **/category/\* to /news/category/$1**
  
  Any tips or ideas ?

  What you'll need to use is a capture group. Something like this for the source:
  
  `/category/(.*$)`
  
  And then the resulting URI would be something like this:
  
  `/news/category/$1`
  
  Each set of `()` is a capture group; they are numbered sequentially, so `$1` will output the first capture group.
  
  If you go to <https://regexr.com/> it will even explain every part of the regex, and what it does:
