Use a number (integer) as argument to narrow down the length of the domain name (excluding the ```.tld``` part!). Without an argument the app returns all domains.
* ```app.py 3 > list.txt``` -> Return domains with 3 chars to the file list.txt. Using ```> file.txt``` overwrites an existing file. Using ```>> file.txt``` appends to existing file or create new file.
## Disclaimer
This is just for fun! There is no guarantee that this app works in any way, shape or form ;-)
