命令一：

ip -4 addr show | grep inet | awk '{ printf "%s ", $2; for (i=5; i<=NF; i++) { printf "%s ", $i }; printf "\n" }' | awk '{print $1, $NF}'

命令二：

忽略 lo 环路网卡

ip -4 addr show | grep inet | awk '{ printf "%s ", $2; for (i=5; i<=NF; i++) { printf "%s ", $i }; printf "\n" }' | awk '{print $1, $NF}' | grep -v "lo"

命令三：

只枚举物理网卡名：

lshw -class network | grep "name:" | awk '{print $3}'

命令四：

只枚举物理网卡名+IP地址：

lshw -class network | grep "name:" | awk '{print $3}' | while read interface; do ip -4 addr show | grep inet | awk -v interface="$interface" '$NF == interface {print $2, $NF}'; done
