带有输入 IP 地址文件和 csv 文件的 Bash 脚本

我有一个带有 ipaddress.txt 输入文件的 bash 脚本，我想将其用于 csv 文件。我想找到 IP，然后显示 A 列的值（目前）。我可能想显示两列或三列。我使用的脚本找到了 IP，但没有打印 A 列中的值。要注意：如果它对答案有帮助，IP 地址位置是 csv 文件的第 16 列或 P 列。

#!/bin/bash

# Read input file with IP addresses
input_file="ipaddress.txt"
while IFS= read -r ip_address; do
    # Search for IP address in CSV file
    csv_file="network-data.csv"
    grep -q "$ip_address" "$csv_file"

    # Print result
    if [ $? -eq 0 ]; then
        echo "$ip_address found in $csv_file"
        awk -F, -v "$ip_address"= '$16 == ip { print $1 }' "$csv_file"
    else
        echo "$ip_address not found in $csv_file"
    fi
done < "$input_file"

这是输出的示例

192.168.1.2 found in network-data.csv
awk: fatal: `192.168.1.2' is not a legal variable name
192.168.1.18 found in network-data.csv
awk: fatal: `192.168.1.18' is not a legal variable name
192.168.1.33 not found in network-data.csv
192.168.1.44 not found in network-data.csv
192.168.1.51 found in network-data.csv
awk: fatal: `192.168.1.51' is not a legal variable name

我使用 AWK 而不是 Bash。 awk -f awkscript.awk ipaddresses.txt csvfile.csv

BEGIN {
    FS = ","; # Assuming CSV fields are separated by commas
}

# Load the IP addresses from file1 into an array
NR == FNR {
    ips[$0] = 1;
    next;
}

# Now we're working with the CSV file
{
    # The IP address is in the 16th field of the CSV
    if ($16 in ips) {
        print $1, $2; # Print columns 1 and 2
    }
}
