将IP转换2、8、16进制程序

转换2进制

#!/bin/ksh
#
#缺省IP为合法地址 :oops:
function b0 {
m=0
while ((m<=$o));do
        echo -n 0;((m+=1))
done
}
set -A ip
n=1
while ((n<=4));do
        ip[$n]=$(echo $1|cut -f$n -d'.');((n+=1))
done
for i in ${ip[*]};do
        typeset -i2 var=$i
        ip=$(echo $var|sed 's/^2#//')
        o=$((8-${#ip}))
        echo -n $(b0)$ip;echo -n .
done|sed 's/.$/\
/g'

转换8进制

#!/bin/bash
echo $1|awk -F. '{ printf "%o.%o.%o.%o\n",$1,$2,$3,$4 }'


转换16进制

#!/bin/bash
echo $1|awk -F. '{ printf "%x.%x.%x.%x\n",$1,$2,$3,$4 }'
