Show active network interfaces on macOS and map them to their corresponding Hardware Port names using ifconfig and networksetup.

ifconfig | awk '/^[a-z0-9]+:/{iface=$1} /status: active/{print iface}' | sed 's/://' | while read iface; do
  port=$(networksetup -listallhardwareports | awk -v dev="$iface" '
    BEGIN {port=""}
    /Hardware Port/ {port=$3; for (i=4; i<=NF; i++) port=port " " $i}
    /Device/ && $2==dev {print port}
  ')
  echo "$iface : $port"
