• Automation: Automate repetitive maintenance tasks to reduce manual effort and prevent human error.

Cron jobs are defined in a file called crontab. Each line in the crontab represents a scheduled task with a specific syntax:

• Systemd Journals: Systemd uses a logging service called journald, which stores logs in a binary format and can be accessed using the journalctl command.
• Syslog: Traditional logging on Linux is handled by syslog services like rsyslog, which logs messages to text files in /var/log/.

journalctl is a command-line utility for querying and displaying logs from journald. It offers powerful filtering and searching capabilities.
