skygts

克隆出来的CentOS6.8 两张网卡的顺序是乱的如下图

如何通过Shell 获取如下信息；
network1= eth2
mac1=00:15:5d:65:7e:8a
ip=192.168.15.146
network2=seth0

1. 
   
2. ip addr | awk 'function p(){if(N~/lo/||N=="")return;print "network"++c"= "N"\nmac"c"="mac"\nip="ip;ip=mac=""}match($0,"[0-9]+: ([^ ]+):",a){p();N=a[1]}/inet /{sub("/.+$","",$2);ip=$2}/link\//{mac=$2}END{p()}'

非常感谢您的帮助。还有一个问题。
运行结果如下：
[root@cloud ~]# ip addr | awk 'function p(){if(N~/lo/||N=="")return;print "network"++c"= "N"\nmac"c"="mac"\nip="ip;ip=mac=""}match($0,"[0-9]+: ([^ ]+):",a){p();N=a[1]}/inet /{sub("/.+$","",$2);ip=$2}/link\//{mac=$2}END{p()}'
network1= eth2
mac1=00:15:5d:65:7e:8a
ip=192.168.15.146
network2= seth0
mac2=00:15:5d:65:7e:8b
ip=
我是想得到如下结果；
[root@cloud ~]# echo $network1
eth2
[root@cloud ~]# echo $mac1
00:15:5d:65:7e:8a
