【问题描述】：

我正在寻找获取多个网站 IP 并将它们输出为 "domain.com:","1.1.1.1" 的最佳方法，以实现这一点我正在考虑使用 nslookup（不确定是否是最佳选择，但我不想要使用 ping)

好吧，我正在尝试类似的东西：

for domain in $(cat domains.txt)
do
   nslookup $domain 8.8.8.8 | awk '/Address: ([[:digit:]]+\.){3}/{gsub(/\.$/,"",$1); printf "\"%s\",\"%s\"\n",$1,$NF}'; done

有了这个，我得到了这个输出：

"Address:","64.233.190.101"
"Address:","64.233.190.138"
"Address:","64.233.190.100"
"Address:","64.233.190.139"
"Address:","64.233.190.113"
"Address:","64.233.190.102"
"Address:","98.137.246.8"
"Address:","98.138.219.231"
"Address:","72.30.35.9"
"Address:","72.30.35.10"
"Address:","98.138.219.232"
"Address:","98.137.246.7"
"Address:","93.184.216.34"

预期输出

"google.com","64.233.190.101"
"google.com","64.233.190.138"
"google.com","64.233.190.100"
"google.com","64.233.190.139"
"google.com","64.233.190.113"
"google.com","64.233.190.102"
"yahoo.com","98.137.246.8"
"yahoo.com","98.138.219.231"
"yahoo.com","72.30.35.9"
"yahoo.com","72.30.35.10"
"yahoo.com","98.138.219.232"
"yahoo.com","98.137.246.7"
"example.com","93.184.216.34"

domains.txt 内容：

google.com
yahoo.com
example.com

我试图这样做，但我无法在输出的"domain.com", 下获得正确的域。

我不确定是使用 $domain 还是 awk，任何人都可以帮助我获得正确的语法。请注意，我需要在 "domain.com", 中请求域，而不是 nslookup 中的 Name:

谢谢。

标签： bash awk ip nslookup

【解决方案1】：

domain="mail.yahoo.com"
nslookup "$domain" 8.8.8.8 | awk -v n="$domain" -F ' +' '$1=="Address:"{print "\""n"\",\""$2"\""}'

输出：

"mail.yahoo.com","87.248.116.12" "mail.yahoo.com","87.248.116.11"

【讨论】：

感谢@Cyrus，它确实有效，但我需要获取请求的域。例如，如果我查找 mail.yahoo.com，我会得到“fd-geoycpi-uno.gycpi.b.yahoodns.net”，“200.152.162.137”，我需要输出“mail.yahoo.com”，“200.152”。 162.137"
酷，谢谢。我喜欢你使用 awk 的方式。
