ufw (a firewall) uses rule numbers when you want to, say, delete a rule. Does it display the rule numbers when you list them with ufw status?
No, of course not, that would be too easy (you’d win the game right away, where’s the fun in that?)
So, instead you have to type ufw status numbered.
Remember kids, beautiful defaults are for newbs and losers. Real gamers play in hard mode.
