Lab 7: Shell Scripting

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. Linux uses cron jobs.

  • 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.
