工作学习 / 学科技术讨论 / cron job question, thanks我有一个crontab running every minutes to check one status. If the status is "fail", then it should send out an email. My question is that I only want the cron jon to send out one email, instead of sending out one email every minute. any ideas? thanks

但是不是还要人工删除这个flag呢？否则永远不再发email了

When the status is OK and the file exists, then remove the file.

create a flag file with last sending timewhen send out email, write to this flag file, then cronjob will check this file before send the mail, you can setup a threshold like 2 hours, the cronjob will check if last email send time is over 2 hours, then send otherwise not

two cron jobs, one for check status and save into file. another check the file and send email. the second one has longer interval.

把出错的信息写到日志文件，第一个cron，查看是否日志文件存在，不存在就send email,存在就append,第二个就是send email ，清除日志文件

记得cron源程序里面是可以设定通知的方式设定为仅仅通知一次的。
