Shell scripting is an integral part of working with cloud computing. Many components of cloud computing are 100% automated. These services must work with minimal or no human interaction. Everything that we’ve done here can be done using a shell script.
In Linux, many processes happen in the background on a set schedule.
Cron is a time-based job scheduler in Unix-like computer operating systems.
Cron enables users to schedule jobs (commands or shell scripts) that run periodically at certain times or dates.
Cron job can run every minute, hour, day, week, month, or year or in any combination.
We are changing our focus from cloud-based services to working with Linux. This lab requires working with the operating system to support the tools instead of setting up a network or web service.
It is strongly recommended that you view the Linux Tutorial to give you an understanding of how Linux operates and some common commands.
