ASSIGNMENT INSTRUCTIONS

Objectives:
To implement a simple job scheduler that executes non-interactive jobs (e.g., jobs that do not have direct user interaction, jobs that can run in the background).

HOW TO WORK ON THIS ASSIGNMENT (EXAMPLE DRAFT/ESSAY)

Instructions on how to set up a simple job scheduler. Here are a few steps you could take:

Define the job specification format: Each scheduled job should have a specification that includes the job name, the command to be executed, and the time the job should be run. You could create a simple text file format with these fields.

Create a parser that can read the job specification files and extract the relevant information.

Keep the job specifications somewhere accessible to the scheduler: Keep the job specifications somewhere accessible to the scheduler. A simple database, such as SQLite, or a plain text file could be used.

Put the scheduler in place: The scheduler should check the job specifications on a regular basis to see if any jobs need to be run. A simple loop that checks the specifications every few seconds could be used. If a job is scheduled to run now, the scheduler should run the specified command.

Handle errors: Make sure to handle any errors that may arise during the job’s execution. If the specified command is invalid, the scheduler should log an error and proceed to the next job.

Provide status information: It may be useful to provide status information on the jobs that have been completed as well as any errors that have occurred. This information could be saved to a log file or displayed on the console.

Test the scheduler: Run a few sample jobs through it to ensure it is working properly.

This is a high-level overview of the steps you could take to put a simple job scheduler in place. The specifics of your implementation will differ depending on the programming language and tools you use.
