 ```
-$ recurse walk [OPTIONS] [ARGS] [START PATH]

 The default behavior of the walk sub-command is to list all file paths that are not hidden in the standard output stream.  Hidden paths are defined as a directory or file that begins with a period (e.g., `.hidden` directory or `.hidden.txt` file).  All directories and files below a hidden directory path are considered hidden.  Directory traversal proceeds to the max directory depth below the user-specified start path `[START PATH]`.
