List "hardware" Network Interfaces Controllers

When using ifconfig or ip link show commands, it lists not only hardware interfaces, but also software interfaces - I would expect only the physically interfaces?

Note: I am running on MacOS.

ip link show

en0, awdl0, llw0, utun0 anpi0 lo0, gif0, stf0 — what OS is this? I suspect MacOS; does it really have iproute2 package?

Sorry, yes it is MacOS. Is iproute2/ip not the successor to ifconfig?

In Linux, yes. I don't know about other systems. I think the original iproute2 package (circa 1999) is only for Linux and it was meant to use new Netlink kernel ABI and unleash the power of new Linux networking possibilities. There is iproute2mac, but **it is not iproute2**, it just mimicks some features of its interface. Also, I think networking utilities is not the right mean to ask about whether interface is physical or logical; they should not make any distinction *by design*. There should be system-specific way to tell; I know one for Linux, but don't know for Mac OS.

Right, thanks "t just mimicks some features"

A quick way could be use ifconfig and grep the entries with an interrupt:

ifconfig |grep -B8 Interrupt

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
