从Linux上下载的文件，用python编辑保持原格式

1.读取的时候加上参数newline=''

with open(os.path.join(current_directory, "deploy.sh"), 'r', newline='', encoding="utf-8") as fileA:
    content = fileA.read()

2.写入的时候加上newline='\n'

with open(deploy_local_path, 'w', newline='\n', encoding="utf-8") as fileB:
    fileB.write(modified_content)
