Renaming a part of the title for multiple folders

Question

Renaming in command prompt

I was wondering if there is a command in Command prompt or Power-shell that can delete the same part of the folders name for all the folders in one go.

Example: For books from the same author but having different titles, I want to keep the books' title but remove author's name.

                   Authors Name The Title                             The Title
              Same Authors Name Different title 1                    Different Title 1
FROM THIS >>> Same Authors Name Different title 2   TO THIS >>>>     Different Title 2
              Same Authors Name Different title 3                    Different Title 3

Thanks!
