rustscan-converter.sh

#!/bin/bash

# Usage
# bash rustscan-converter.sh ports.txt

# Check if the input file exists
if [ ! -f "$1" ]; then
    echo "Input file '$1' not found."
    exit 1
fi

# Read the input file line by line
while IFS= read -r line; do
    # Extract the IP address and port numbers using awk
    ip=$(echo "$line" | awk -F ' -> ' '{print $1}')
    ports=$(echo "$line" | awk -F ' -> ' '{print $2}' | sed 's/\[//;s/\]//;s/,/\n/g')

    # Loop through the port numbers and print in the desired format
    while IFS= read -r port; do
        echo "$ip:$port"
    done <<< "$ports"
done < "$1"
