【问题描述】：

我刚刚完成了对我内部网络上的主机的扫描...它对 smb 很敏感，我需要从扫描结果中 grep 选择行

    root@kali:~# nmap -p445 --script smb-vuln-* 192.168.99.50
Starting Nmap 7.80 ( https://nmap.org ) at 2020-01-13 00:21 EET

Host is up (0.19s latency).

PORT    STATE SERVICE
445/tcp open  microsoft-ds

Nmap done: 1 IP address (1 host up) scanned in 7.11 seconds

我只想grep testes vuln的名称和状态：像这样

| smb-vuln-ms08-067: 
|   VULNERABLE:
| smb-vuln-ms10-054: false
|_smb-vuln-ms10-061: false
| smb-vuln-ms17-010: 
|   VULNERABLE:

标签： grep nmap scanning

【解决方案1】：

通过下一个管道过滤nmap的输出：

sed -e '/^..smb-vuln-[^:]*: false/p' -e '/^..smb-vuln-[^:]*: *$/{n;p}' -e d

解释：

第一个 sed 命令打印以特定模式开头的行并以“：假”结尾
第二个命令打印开始的行具有相同的模式，但在“：”之后没有任何内容，还有下一行； {n;p} 表示添加下一行并打印
第三条命令d 会从输出中删除所有其他内容
