Nmap输出，IP和MAC地址在同一行

Question

鉴于this question的答案，

我想知道如何从以下输出中获取：

Nmap scan report for 192.168.1.38
Host is up (0.0092s latency).
MAC Address: B8:78:2E:XX:XX:XX (Apple)
Nmap scan report for 192.168.1.39
Host is up (0.0092s latency).
MAC Address: 40:6C:8F:XX:XX:XX (Apple)
Nmap scan report for 192.168.1.201
Host is up (0.019s latency).
MAC Address: 3C:DF:A9:XX:XX:XX (Arris Group)
Nmap done: 256 IP addresses (3 hosts up) 

scanned in 1.77 seconds

以下解析结果输出：

192.168.1.38 B8:78:2E:XX:XX:XX
192.168.1.39 40:6C:8F:XX:XX:XX
192.168.1.201 3C:DF:A9:XX:XX:XX

谢谢。

Answer 1

以下awk可能会帮助你。

awk '
/Nmap scan report/{
  val=$NF;
  next
}
/MAC Address:/{
  sub(/.*Address: /,"");
  sub(/ .*/,"");
  print val,$0
}
'   Input_file

Answer 2

$ awk '/Nmap scan/{ip=$NF;next}ip && /MAC/{print ip, $3}' infile
192.168.1.38 B8:78:2E:XX:XX:XX
192.168.1.39 40:6C:8F:XX:XX:XX
192.168.1.201 3C:DF:A9:XX:XX:XX

$ awk '/Nmap scan|MAC/{gsub(/\(.*/,"");printf "%s%s", $NF, ++c%2?OFS:RS}' infile
192.168.1.38 B8:78:2E:XX:XX:XX
192.168.1.39 40:6C:8F:XX:XX:XX
192.168.1.201 3C:DF:A9:XX:XX:XX

输入：

$ cat infile
Nmap scan report for 192.168.1.38
Host is up (0.0092s latency).
MAC Address: B8:78:2E:XX:XX:XX (Apple)
Nmap scan report for 192.168.1.39
Host is up (0.0092s latency).
MAC Address: 40:6C:8F:XX:XX:XX (Apple)
Nmap scan report for 192.168.1.201
Host is up (0.019s latency).
MAC Address: 3C:DF:A9:XX:XX:XX (Arris Group)
Nmap done: 256 IP addresses (3 hosts up)
