查看所有网卡，状态、光电类型、ip、广播地址、掩码

1、命令如下

(
string='|%-3s|%-18s|%-10s|%-10s|%-10s|%-16s|%-16s|%-16s|';
br="`echo $string|grep -Eo '[0-9]+'|awk '{s=s+$1}END{s=s+NR;for(i=0;i<=s;i++){printf "-"};print""}';`";
printf1(){ printf "$string\n" NO Device Status Type Speed Ipaddr Mask Bcast; };
printf2(){ printf "$string\n" $NO $DEVICE $STATUS $TYPE $SPEED $IPADDR $MASK $BCAST; };
echo $br;printf1;echo $br;
NO=;
for i in `ip a|awk -F ':' '/^[0-9]/{print $2}'|sort`; do
DEVICE=$i;
STATUS=`ip a|grep ":.$i:"|awk '{print /LOWER_UP/?"UP":"DOWN"}'`;
TYPE=` ethtool $i |grep 'Supported ports' |sed 's/]//g' |awk -F '[' '{print $2}'|sed 's/ //g'`;
SPEED=` ethtool $i |awk '/Speed/{print $NF}'`;
IPADDR=`ifconfig $i |grep -Eo '([0-9]+\.){3}[0-9]{1,3}'|awk 'NR==1'`;
MASK=` ifconfig $i |grep -Eo '([0-9]+\.){3}[0-9]{1,3}'|awk '/^255/'`;
BCAST=` ifconfig $i |grep -Eo '([0-9]+\.){3}[0-9]{1,3}'|awk 'NR>1&&!/^255/'`;
[ "x"$STATUS == "x" ] && STATUS='-';
[ "x"$TYPE == "x" ] && TYPE='-';
[ "x"$SPEED == "x" ] && SPEED='-';
[ "x"$IPADDR == "x" ] && IPADDR='-';
[ "x"$BCAST == "x" ] && BCAST='-';
[ "x"$MASK == "x" ] && MASK='-';
printf2;
NO=`echo $NO|awk '{print $1+1}'`;
done >/dev/null;
echo $br;
route -n|grep ^0.0.0.0|awk '{print "GATEWAY: ",$2," "$NF}';
echo $br;
)

2、使用：

[root@localhost eversec]# sh hhh
------------------------------------------------------------------------------------------------------------
|NO |Device |Status |Type |Speed |Ipaddr |Mask |Bcast |
------------------------------------------------------------------------------------------------------------
|0 |lo |up |- |- |127.0.0.1 |255.0.0.0 |- |
|1 |eth0 |up |TP |1000Mb/s |10.233.253.66 |255.255.255.248 |10.233.253.71 |

------------------------------------------------------------------------------------------------------------

3、注解：

NO：序号
Device: 网卡名称
Status: 网卡状态
Speed：速度
Type: 网卡类型（光口：FIBRE、电口：TP）
Ipaddr: ip地址
Mask: 掩码
Bcast: 广播地址
