A painter and a black cat

こんなシェルスクリプトを作った。nslookupがインストールされていることが前提

whereDoYouComeFrom.sh¶

#!/bin/sh

if [ $# = "0" ]
then
        echo "ex>${0} [ip address].."
        exit 1
fi

for WORD in "${@}"
do
        REVERS_IP=`echo ${WORD}|awk -F'.' '{print $4,".",$3,".",$2,".",$1}'|sed -e 's/ //g'`
        COUNTRY=`nslookup -type=TXT ${REVERS_IP}.cc.wariate.jp|grep '"'|awk -F'"' '{print $2}' `
        echo "${WORD}   ${COUNTRY}"
done

exit 0

で、以下みたいに使う
