shell转换IP

老大写的一个shell转换IP的 很好用 ，分享下！

#!/bin/bash
hexip=""
hextoip() {
    hex=$1
ip1=`printf "%d." 0x${hex:6:2}`
ip2=`printf "%d." 0x${hex:4:2}`
    ip3=`printf "%d." 0x${hex:2:2}`
ip4=`printf "%d" 0x${hex:0:2}`
ip=$ip1$ip2$ip3$ip4
hexip=$ip
#return $ip
}


iptohex() {
    IFS=.
    for str in $1
    do
        printf "%02X" $str
    done
}


iptoaddr ()
{
#exec < $1
#while read a
for a in `cat $1`
do
#sring=`curl -s  "http://ip138.com/ips138.asp?ip=${a}&action=2" |grep '<ul class="ul1"><li>' |awk -F'[><]+' '{print $5}'`

#echo $a $hex
