Not liking Venkon Web interface? Use Subvenkon!
From Sam (CoffeeJunkie). I find venkon very useful at the time to gather subdomains, but one of the problems that I had was constantly copy pasting and having couple problems at the time to pipe the results. That’s why I created Subvenkon which does the same thing than venkon, but from the terminal and without duplicates or strange strings so it’s easier to pipe it.

It’s pretty straight forward. Just type:
python subvenkon.py -d domain.com
This is an example with an open scope program from Hackerone which is AT&T
Once the subdomains have been gathered, there will be a file named as the domain and with the results
