求：判断某一ip地址是否属于某一ip网段的脚本

kaka_sun

  分的确是点的给老大的，奇怪却分给了另一个好心人！！！！

kaka_sun

供参考：

IPLIST=$(cat ip)
NETLIST=$(cat network)

for ip in ${IPLIST}
do
  echo "IP: $ip";
  for network in ${NETLIST}
  do
    [ "$(ipcalc -n $ip/${n ...

好像不行啊，我测试了一下，不行

什么错误？我只简单测了一下。

这是我得出的结果，为何不一样呢？

kaka_sun

IPLIST=$(cat ip)
NETLIST=$(cat network)

for ip in ${IPLIST}
do
  echo "IP: $ip";
  for network in ${NETLIST}
  do
    [ "$(ipcalc -n $ip/${network#*/})" = "$(ipcalc -n $network)" ] &&
                              echo -e "$ip\tis in $network" ||
                              echo -e "$ip\tis not in $network"

  done
  echo "--------------------------------";
done


这样就行了

看来是ipcalc 的输出不一样。我用sed把第一行去掉了。没试其它方式。
