The built-in helper (-helper) provides three options for processing wordlists in the wordlists/ directory:
- Split lines -- Remove non-alphabetic characters and split into separate lines.
- Filter by length -- Keep only words of a specific length.
- Save by length -- Split a wordlist into separate files by word length (e.g.
4char.txt,5char.txt).
