- if [ -z "$1" ]
- then
- echo "sh dig_all.sh www.a.com";
- exit;
- fi
- #ready to test dns ip
- dns_hosts=("202.106.0.20" "202.106.196.115")
- #dig domain
- domain=$1
- for((i=0;i<${#dns_hosts[@]};i++))
- do
- dns_host=${dns_hosts[$i]};
- result=`dig +short @$dns_host $domain`
- if [ "$?" = "0" ]
- then
- echo "dig +short @$dns_host $domain success [$result]"
- else
- echo "dig +short @$dns_host $domain fail"
- fi
- done
执行结果：
- [root@localhost scp]# sh dig_all.sh www.baidu.com
- dig +short 202.106.0.20 www.baidu.com success [www.a.shifen.com.
- 61.135.169.105
- 61.135.169.125]
- dig +short 202.106.196.115 www.baidu.com success [www.a.shifen.com.
- 61.135.169.105
- 61.135.169.125]
