probabely＆QUOT;环路QUOT;和＆QUOT;输出＆QUOT;没有在我的bash脚本正常工作

问题描述

我写了下面的脚本：

#!/bin/bash

echo "Reading data - headers - both"

if [ $# -ne 3 ]; then
    echo "Usage: ./nmap <port-range> <ip-list> <d || h || b>"
    exit 1
fi

rm -f /tmp/right.txt 1>/dev/null 2>/dev/null
rm -f /tmp/wrong.txt 1>/dev/null 2>/dev/null

output=""
if [ $3 == h ]; then
    while read -r -u3 port; do
    while read -r -u4 ip; do
#       echo -en "\n$ip $port: "
        OUT=$( nmap -p "$port" --script=http-headers.nse "$ip" | awk 'NR>=7 && NR<=10')
     #   [[ $OUT == *Apache* ]] && $(echo -en "$ip  $port\n" >> /tmp/right.txt) || $(echo -en "$ip  $port\n" >> /tmp/wrong.txt)
        [[ $OUT == *Apache* ]] && output="$output `echo -en "\n$ip -------------------- $port "`" && echo -e "$output" | column -t >> /tmp/right.txt || output="$output `echo -en "\n$ip -------------------- $port "`" && echo -e "$output" | column -t >> /tmp/wrong.txt
    done 4< "$2"
    done 3< "$1"

    echo -e "$output" | column -t

elif [ $3 == d ]; then
    echo data
elif [ $3 == b ]; then
    echo both
fi

我希望我的输出有两个文件：

I expect my output have two files:

cat right.txt
ip1 ..... port1
ip2 ..... port1
ip2 ..... port2
ip3 ..... port3
.
.
.

cat wrong.txt
ip1 ..... port1
ip2 ..... port1
ip2 ..... port2
ip3 ..... port3
.
.
.

，但它不能正常工作...

but it doesn't work properly...

任何想法？

   #!/bin/bash

    echo "Reading data - headers - both"

    if [ $# -ne 3 ]; then
        echo "Usage: ./nmap <port-range> <ip-list> <d || h || b>"
        exit 1
    fi

    join -j 2 $2 $1 > temp.txt

    headers()
    {
         while read -r ip port
         do
            printf "ip: %s  port:%d \n" $ip $port
            OUT=$(nmap -p "$port" --script=http-headers.nse "$ip" | tac | awk -F: 'NR<=13&&/Apache/{print $2; exit}')
            if [[ "$OUT" == *Apache* ]]; then
                echo $ip $port >> /tmp/right.txt
            else
                echo $ip $port >> /tmp/wrong.txt
            fi
         done < temp.txt
    }

    case $3 in
      "h") headers ;;
      "d") echo data;;
      "b") echo both;;
      "*") echo "wrong input"
           exit;;
    esac
