使用bash和awk從多個網站提取IP

Question

我正在尋找獲取多個網站IP並將其輸出為"domain.com:","1.1.1.1"的最佳方法，以實現此目標，我正在考慮使用nslookup （不確定是否是最佳選擇，但我不想使用ping）

好吧，我正在嘗試類似的東西：

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

這樣，我得到以下輸出：

"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"

預期產量

"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內容：

google.com
yahoo.com
example.com

我試圖這樣做，但是在輸出的"domain.com",下找不到正確的域。

我不確定是否使用$ domain或awk，誰能幫助我獲得正確的語法。 請注意，我需要在"domain.com",請求的域"domain.com",而不是nslookup中的“ Name:

謝謝。

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

輸出：

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