'ip addr' displays all the information 'ip link' does about links and then adds address info to that, so that is usually enough unless you're looking for. ip -s addr if you want packet stats too (which I almost never do, so I'm glad it's off by default). ('ip link' is still valuable because that's what you use to *configure* the link layer: you can't use ip addr to do that.)

But it's crazy that I have to type `ip -s addr` and can't `ip addr -s`, when command-subcommand-options is *so* much more natural. `tc` has this problem too. And `ip` doesn't understand `-h` at *all*, which is a cardinal sin for a Unix utility. (Though what can one expect from a Cisco-ism.)

I think it's supposed to indicate that the -s option applies to many ip subcommands. Quite a lot of other commands these days do the same thing: git for one. I find it a bit annoying, too, but it does allow git -P diff and git diff -P to mean different things... which matters a lot for a metastasized mega-command like git and... not so much at all for ip.
