Linux 所有网卡统计查看小命令

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
