Why is my CronJob not running in Linux?

If your CronJob is not running in Linux, several factors might be causing the issue. First, check if the cron service is active with sudo systemctl status cron. Ensure that the CronJob is correctly defined in the crontab file (crontab -e) and follows the correct syntax. Verify that the script or command being executed has the correct permissions and paths. Also, check the system’s timezone, as mismatches can prevent jobs from running at expected times. Review the cron logs in /var/log/syslog or /var/log/cron for error messages to help identify the problem.
