在julia中查找替换文件内容的正确方法是什么？

function replace_file_content(filename::AbstractString, search_pattern::AbstractString, replacement::AbstractString)
    # 读取文件内容
    lines = readlines(filename)

    # 创建一个新的文件来保存替换后的内容
    new_filename = filename * ".new"
    new_file = open(new_filename, "w")

    # 遍历文件的每一行
    for line in lines
        # 使用正则表达式查找匹配的内容
        if occursin(search_pattern, line)
            # 替换匹配的内容
            new_line = replace(line, search_pattern => replacement)
            write(new_file, new_line)
        else
            write(new_file, line)
        end
    end

    # 关闭文件
    close(new_file)

    # 删除原始文件
    rm(filename)

    # 重命名新文件为原始文件名
    mv(new_filename, filename)
end
