Duplicate a directory and assign it a new name!
Please use generator-tcg if you are looking for a more feature-rich solution.
Install Node, and then DupeJS.
npm install -g dupejs
Run the "dupejs" command, and the two required arguments (which corresponds to the existing directory that needs to be duplicated, and the desired name for the new directory). The copying will be carried out recursively, so all nested directories and files will be found within the newly-created parent directory.
# general
