Designing command-line applications for scheduled execution
Command-line applications are still running amongst us. They are the backbone of large corporations. They are those faithful workers that converts the raw data into beautiful reports while we are asleep. They are those tireless gatekeepers that constantly help us check whether our mission-critical servers are alive and notify us when they detect any anomalies.
Part of what I do for my job is to ensure that those scheduled jobs in my department run smoothly, and in the event that they don’t, run them manually to get the neccessary output for the day and make sure that they continue to run automatically for subsequent days. These scheduled jobs consist of running command-line applications hourly, daily or monthly.
To anticipate future needs, I had spent some time to come out with some guidelines on how I will design my command-line applications meant for scheduled execution.
