如何在具有178.000行的文件中的IP之前添加自定义字符？

我有一个文本文件，其中包含来自myip.ms的178.000行列入黑名单的IP（12 MB），格式为：

1.2.81.113           # 2014-09-10, 1.2.81.113, CHN, 51
1.2.82.108           # 2014-09-10, 1.2.82.108, CHN, 51
1.2.83.179           # 2014-09-11, 1.2.83.179, CHN, 51
1.2.86.210           # 2014-09-07, 1.2.86.210, CHN, 51
1.2.109.22           # 2014-09-06, 1.2.109.22, CHN, 51

现在，我需要在每行之前添加“ Require not ip”，如下所示：

Require not ip 1.2.81.113            # 2014-09-10, 1.2.81.113, CHN, 51
Require not ip 1.2.82.108            # 2014-09-10, 1.2.82.108, CHN, 51
Require not ip 1.2.83.179            # 2014-09-11, 1.2.83.179, CHN, 51
Require not ip 1.2.86.210            # 2014-09-07, 1.2.86.210, CHN, 51
Require not ip 1.2.109.22            # 2014-09-06, 1.2.109.22, CHN, 51

如何以最小的努力来达到我的最佳配置，以达到我的apache配置？或者是否有更好的方法来包括黑名单？

<Directory /var/www/>
<RequireAll>
    Require all granted
    # IP Blacklists
    Include full_blacklist_database.txt
</RequireAll>
</Directory>

在Java中，您可以执行以下操作：

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileReader;
import java.io.FileWriter;

import javax.swing.JOptionPane;

public class StringAppender {

public static void main(String[] args) {
    String fileIn = JOptionPane.showInputDialog("Enter the path to the file");
    try{
        if(new File(fileIn).exists()){
            StringBuilder sb = new StringBuilder();
            BufferedReader br = new BufferedReader(new FileReader(fileIn));

            String tmp;
            while((tmp = br.readLine()) != null)
                sb.append("Require not ip " + tmp + "\n");

            br.close();
            BufferedWriter out = new BufferedWriter(new FileWriter(fileIn + ".new.txt"));
            out.write(sb.toString());
            out.close();
            JOptionPane.showMessageDialog(null, "Done! New file saved as: " + fileIn + ".new.txt");
        }else{
            JOptionPane.showMessageDialog(null, "Requested file doesn't exist!");
        }
    }catch(Exception e){
        JOptionPane.showMessageDialog(null, "Unable to perform changes!");
    }
}
}

预编译的版本可以在此处下载。要将cd运行到dir并执行java StringAppender
