Cron工作每三天 [英] Cron job every three days

问题描述

是否可以每三天运行一次 cronjob ？

Is it possible to run a cronjob every three days? Or maybe 10 times/month.

推荐答案

每三天运行一次...

Run it every three days...

0 0 */3 * *

如何？

如果你想要在一个月的特定日子里运行，例如第1，第4，第7等等，那么你只需要一个

If you want it to run on specific days of the month, like the 1st, 4th, 7th, etc... then you can just have a conditional in your script that checks for the current day of the month.

if (((date('j') - 1) % 3))
   exit();

或者，如@mario指出，您可以使用date（'k'）获取日期而不是基于每月的日期。

or, as @mario points out, you can use date('k') to get the day of the year instead of doing it based on the day of the month.
