Understanding Cron Jobs

The software utility Cron is a time-based job scheduler in Unix-like computer operating systems. Users that set up and maintain software environments use cron to schedule jobs (commands or shell scripts) to run periodically at fixed times, dates, or intervals.

Tips for Debugging

Always verify your server's timezone when setting up cron jobs. A job set to run at 12:00 AM UTC might run at 7:00 PM EST the previous day. Use absolute paths in your scripts to avoid "command not found" errors.
