linux下基于指定目录及子目录下所有文件中指定字符串进行替换

1. 使用sed命令进行替换:

   sed -i 's/old_string/new_string/g' /path/to/directory/*
   

2. 使用find命令结合sed进行替换:

   find /path/to/directory -type f -exec sed -i 's/old_string/new_string/g' {} +
   

3. 使用grep命令找到包含指定字符串的文件，再使用sed进行替换:

   grep -rl 'old_string' /path/to/directory | xargs sed -i 's/old_string/new_string/g'
   

4. 使用awk命令进行替换:

   awk '{gsub(/old_string/, "new_string"); print > FILENAME}' /path/to/directory/*
   

5. 使用perl命令进行替换:

   perl -pi -e 's/old_string/new_string/g' /path/to/directory/*
   

6. 使用Python脚本进行替换:

   import os
   
   def replace_string(path, old_string, new_string):
       for root, dirs, files in os.walk(path):
           for file in files:
               file_path = os.path.join(root, file)
               with open(file_path, 'r') as f:
                   content = f.read()
               content = content.replace(old_string, new_string)
               with open(file_path, 'w') as f:
                   f.write(content)
   
   replace_string('/path/to/directory', 'old_string', 'new_string')
