What command is used to interact with journald?

The command used to interact with journald is journalctl. This command provides an interface for querying and displaying logs from the journal, which is managed by the systemd-journald service. Journalctl allows users to view and filter log entries based on various parameters, such as time, service, severity level, and more.

The utility is essential for system administrators and developers when troubleshooting and monitoring system events since it aggregates logs from various sources, including the kernel and system services, into a centralized location. It offers options to view logs in real-time, export logs, and display logs in various formats, enhancing its utility for managing system logs efficiently.

Other options like systemctl are primarily used to manage system services and their states. Logctl is not a standard command in this context, and syslog generally refers to a more traditional logging mechanism rather than interacting specifically with the systemd logging system.
