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 " NO Device Status Type Speed Ipaddr Mask Bcast; }; printf2(){ printf "$string " $NO $DEVICE $STATUS $TYPE $SPEED $IPADDR $MASK $BCAST; }; echo $br;printf1;echo $br; NO=0; 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 2>/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

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
