A quick introduction to cron for people who want to manage scheduled and recurring tasks on Linux systems. This is useful for system administrators, developers/programmers, and everyone who wants to do things like
— occasionally cleaning out old files
— removing development clutter
— scheduling things on servers or other remote machines
— If you have something more exciting, leave it in the comments and Ill put it here :-D.
We also touch on slightly more advanced topics such as security considerations and cron.{allow,deny}
В каком формате записываются задачи планировщика cron, где лежат файлы запланированных задач для новых установленных программ, и куда класть скрипты для их выполнения ежечасно, ежедневно, еженедельно и ежемесячно.
