Querying domains
Listing user rules is useful, but what if we want to simply check if a rule exists?
A solution would be to run:
tblock -l | grep "example.org"
However, with this solution, we can't see which filter list owns the rule. But it's alright, because TBlock 2.2.0 introduced a new option for this purpose!
Simply run:
tblock -W example.org
Or:
tblock --which example.org
