Nmap Greppable Parser

A Bash script to extract and format open ports from greppable Nmap scan results.

📌 Features

• Parses Nmap greppable (-oG) output.
• Extracts IP addresses and their open ports.
• Formats the output as:

  <IP_ADDRESS>    <PORT1>,<PORT2>,<PORT3>
  

• Efficient processing using grep and awk.

🌜 Usage

./parse.sh <nmap_results_file>

Example:

Input (Nmap Greppable Format)

Host: 192.168.1.1 ()    Ports: 22/open/tcp//ssh///, 80/open/tcp//http///, 443/open/tcp//https///
Host: 192.168.1.2 ()    Ports: 3306/open/tcp//mysql///

Output

192.168.1.1    22,80,443
192.168.1.2    3306

🖥️ Generating Nmap Greppable Output

nmap -p- -oG nmap_results.txt 192.168.1.0/24

🔍 How It Works

• Extracts lines containing "Ports" using grep.
• Uses awk to:
  • Print the IP address (second field).
  • Extract and format open ports in a comma-separated list.
