  • ```sh
  • perl-rename -nv 'regex' **/*
  • ```
  • #### Breakdown:
  • - **-n**: *Dry run*—no files are actually renamed; it only shows what *would* happen.
  • - **-v**: *Verbose*—prints each renaming operation in the format:
  • ```
  • original_filename renamed as new_filename
  • ```
  • - **'regex'**: Your Perl regex describing how names should change.
  • - **`**/*`**: Expands to all files in the current directory and all its subdirectories (requires your shell to support globstar, e.g., Bash 4+ with `shopt -s globstar` enabled).
  • ```sh
  • perl-rename -nv 'regex' **/*
  • ```

```sh

#### Breakdown:
- **-n**: *Dry run*—no files are actually renamed; it only shows what *would* happen.
- **-v**: *Verbose*—prints each renaming operation in the format:
  
  ```
  original_filename renamed as new_filename
  ```
- **'regex'**: Your Perl regex describing how names should change.
