ifconfig命令结果过滤的问题

sailer_sh

系统有2块网卡，ifconfig命令的结果

1. 
   
2. eth0      Link encap:Ethernet  HWaddr 00:0E:7F:B3:11:12  
   
3.           inet addr:192.168.1.81  Bcast:192.168.1.127  Mask:255.255.255.192

要求过滤输出网卡名，ip地址，mac地址，像这样：

1. 
   
2. eth0 192.168.1.81 00:0E:7F:B3:11:12
   
3. eth1 10.0.0.81 00:0E:7F:B1:56:CC

不知道sed或awk能不能一性输出这个结果？

ywlscpl

1. ifconfig |awk '$1~/^eth/{i=$1;mac=$NF}$1" "$2~/^inet addr:/{print i,m[split($2,m,":")],mac}'

ifconfig |
        sed -n '/^eth[0-9]\+ /{N; s/\n//; s/addr://; p}' | awk '{print $1, $7, $5}'

严格一点的写法:

ifconfig | sed -n '/^[^ ]/{ /lo/! {N; s/\n//; s/addr://; p}}' | awk '{print $1, $7, $5}'

greendays

awk '/eth/{print;getline;print}' ur |sed -rn 'N;s/\n//;s/addr://p' | awk '{print $1,$7,$5}'

greendays

sed -rn '/eth/{N;s/\n//;s/addr://;p}' ur | awk '{print $1,$7,$5}'

lucash

ifconfig | awk -v RS='\n\n' -F' +|\t+|inet addr:' '/HWaddr/{print $1,$8,$5};!/HWaddr/{print $1,$7,$4}'

greendays

sed -rn '/eth/{N;s/\n[ \t]+//;s/(eth[0-9]).*(..:..:..:..:..:..) .*addr.*) Bcast.*$/\1 \3\2/;p}' ur

greendays

sed -rn '/eth/{N;s/(eth[0-9]).*(..:..:..:..:..:..).*addr.*) Bca.*$/\1 \3\2/;p}' ur
