Small script to generate a list of ports to be scanned from the port detected by nmap

nmapBasic2Full.sh

#!/bin/bash
declare -a tcp=()
declare -a udp=()
while IFS= read -r line; do
    port=$(echo $line | awk '{print $4}')
    [[ "$port" =~ "tcp" ]] && tcp+=("${port%%/*}") || udp+=("${port%%/*}")
done < "${1:-/dev/stdin}"
IFS=,
echo -n "-sS -p "
echo "${tcp[*]}"
echo -n "-sU -p "
echo "${udp[*]}"
