摘　　要：同城用户因对象不同,需求各异,文章基于用户的特殊需求,编写Shell程序进行气象数据格式自动转换和主动分发推送,结合Linux操作系统多线程并发和任务定时触发的特点实现了程序的自动高效运行。此外,数据加锁机制的应用有效保证了用户端读取数据的完整性,为同城用户及时稳定的气象数据应用服务提供了技术保障。Users in the same city have different needs because of different objects.Based on the special needs of users,this paper writes Shell program for automatic conversion of meteorological data format and active distribution push.Automatic and efficient running of program is realized by combining multithread concurrency and task timing trigger in Linux operating system.In addition,the application of the data locking mechanism effectively ensures the integrity of the data read by the user,and provides technical support for the timely and stable meteorological data application service of the same city users.
