Linux Scheduling for Absolute Beginners
In my first article, I provided some basic understanding of how scheduling on Linux operating system works and also gave some examples of how to schedule jobs using cron at different date and times. If you haven’t read it, please read Scheduling for Absolute Beginner first.
This article will provide some additional detail that I may have missed and it will mostly give examples of many different neat tricks you can do in a crontab file. For example, you can write single line cron entries to gather system statistics and email you details without even writing a script in a separate file.
