Explanation

The systemd is a system and service manager for Linux systems that provides a standard way to control and monitor system services. The systemd uses various commands and tools to manage and troubleshoot system services, such as systemct1, sysctl, and journalctl. The systemct1 command is used to start, stop, enable, disable, restart, reload, status, and list system services. The sysctl command is used to configure kernel parameters at runtime. The journalctl command is used to view and filter the logs of system services. To investigate a service that is not starting up, the administrator can use the journalctl command with the -xu option. The -x option enables verbose output that includes explanatory text and priority information. The -u option filters the output by a specific unit name, such as network.service. Therefore, the command journalctl -xu network will show detailed logs of the network service, which can help identify the cause of the failure.
