击：增加输入前缀挖输出

Question

当我这样做，

$dig axfr @ns2.3u.net weclapp.com 

我得到的输出结果为，

; <<>> DiG 9.8.1-P1 <<>> axfr @ns2.3u.net weclapp.com 
; (1 server found) 
;; global options: +cmd 
weclapp.com.  300 IN SOA ns1.3u.net. ops.3u.net. 2015052602 21600 3600 604800 180

现在我想给每个输出线加与来自读取数文件。我这样做，

#Input.txt 
1,weclapp.com,ns2.3u.net 

#test.sh 
while IFS=, read -r n d s;do 
     printf "$n,%s\n" $(dig axfr @"$s" "$d") 
done < Input.txt 

#d is domain , #s is name server ,#n is number from the input file. 

当我运行它$sh tesh.sh，我得到的输出为。

它要像，

1,; <<>> DiG 9.8.1-P1 <<>> axfr @ns2.3u.net weclapp.com 
1,; (1 server found) 
1,;; global options: +cmd 
1,weclapp.com.  300 IN SOA ns1.3u.net. ops.3u.net. 2015052602 21600 3600 604800 180 
1,...... 

可有人就如何实现增加input number (n)下面挖命令输出建议？

Answer 1

您可以修改你的脚本是这样的：

while IFS=, read -r n d s;do 
    dig axfr @"$s" "$d" | sed "s/^\(.\)/$n,\1/" 
done < Input.txt 

sed将跳过空行添加$n,但前缀上的所有其他线路$n,。

输出：

1,; <<>> DiG 9.8.3-P1 <<>> axfr @ns2.3u.net weclapp.com 
1,; (1 server found) 
1,;; global options: +cmd 
1,weclapp.com.  300 IN SOA ns1.3u.net. ops.3u.net. 2015052602 21600 3600 604800 180
