如何使文件中IP掩码转换

hbczjzc

IP.TXT 文件如下：

add address=1.24.0.0/13 comment="" disabled=no list=List_ChinaUnicom
add address=1.56.0.0/13 comment="" disabled=no list=List_ChinaUnicom
add address=1.93.0.0/16 comment="" disabled=no list=List_ChinaUnicom
add address=1.188.0.0/14 comment="" disabled=no list=List_ChinaUnicom
add address=14.204.0.0/15 comment="" disabled=no list=List_ChinaUnicom
add address=27.0.128.0/24 comment="" disabled=no list=List_ChinaUnicom
add address=27.8.0.0/13 comment="" disabled=no list=List_ChinaUnicom
add address=27.36.0.0/14 comment="" disabled=no list=List_ChinaUnicom
add address=27.40.0.0/13 comment="" disabled=no list=List_ChinaUnicom
add address=27.50.128.0/17 comment="" disabled=no list=List_ChinaUnicom
.......

转换后文本内容 （可用 ipcalc 转换掩码）

route inside 1.24.0.0 255.248.0.0 192.168.1.254 1
route inside 1.56.0.0 255.248.0.0 192.168.1.254 1
route inside 1.93.0.0 255.255.0.0 192.168.1.254 1
route inside 1.188.0.0 255.252.0.0 192.168.1.254 1
route inside 14.204.0.0 255.245.0.0 192.168.1.254 1
route inside 27.0.128.0 255.255.255.0 192.168.1.254 1
.....

可用 ipcalc 转换掩码

1. #!/bin/bash
   
2. 
   
3. while read line; do
   
4.         ip=(`echo $line | sed -r 's/add address\=([^ ]*)\/([0-9]+) .*/\1 \2/'`)
   
5.         subbet=$(( 32 - ${ip[1]} ))
   
6.         let "mask = 2**32 - 2**$subbet"
   
7.         echo "route inside ${ip[0]} $(( $mask >> 24 )).$(( $mask >> 16 & 255 )).$(( $mask >> 8 & 255 )).$(( $mask >> 0 & 255 )) 192.168.1.254 1"
   
8. done <$1

1. awk -F '[= ]' '{split($3,ip_pre,"/");cmd="ipcalc -m "$3;cmd | getline netmask;print "route inside "ip_pre[1]" "substr(netmask,9)" 192.168.1.254 1";close(cmd)}'
