  - Use bash function as wrapper to echo and group each command being
    performed along with its stdout/stderr messages.

  - Use regex search of '/.' to find and exclude dotfile paths instead
    of resolving each basename of each parent directory in each path.

  - Use double quotes to handle file names with special characters.

    - Escape out double quotes when they appear in file names.

  - Note: Incrementing major version number due to added dependency of
    GNU Parallel 20210822
