ip eg:
# ip a
# ip a a 192.168.1.99/24 dev enp160
The first incantation - ip address (you can abbreviate whilst it is unambiguous) gets you a quick report of interfaces, MAC, IPs and so on. The second command assigns another IP address to an interface. Handy for setting up devices which don’t do DHCP out of the box or already have an IP and need a good talking to.
Oh and you can completely set up your IP stack, interfaces and routing etc with it. Throw in nft or iptables (old school these days - sigh!) for filtering and other network packet mangling shenanigans.
Who on earth actually cares? Those 12% are probably not really wrong either, apparently.
Can you fiddle up a weird black screen with lots of $ and # symbols? Yes, its a Unix and its probably Linux.
MacOS is odd because I say so and because most users of it will insist on their screen being darkened and brightened at the same time. I don’t like black being rammed into my eyes.
