1. 导入必要的模块

import os
import shutil

2. 定义需要查找的字符串、文件夹路径和汇总文件路径，以及一个空列表用于储存匹配的文件

search_string = "特定字符串"
folder_path = "文件夹路径"
output_path = "汇总文件路径"

matched_files = []

3. 遍历文件夹中所有文件，查找是否包含特定字符串

for filename in os.listdir(folder_path):
    with open(os.path.join(folder_path, filename), "r") as file:
        if search_string in file.read():
            matched_files.append(filename)

4. 对于匹配的文件，复制特定字符后的所有行并将它们写入汇总文件

with open(output_path, 'w') as output_file:
    for file in matched_files:
        with open(os.path.join(folder_path, file), "r") as input_file:
            copying = False
            for line in input_file:
                if search_string in line:
                    copying = True
                if copying:
                    output_file.write(line)

这样就可以在汇总文件中查找特定字符串并查看其后续的记录了。
