Systemctl is a command-line tool used in Linux to control and manage the systemd service manager. It allows starting, stopping, restarting, enabling/disabling, and checking the status of services.
Commonly used systemctl commands include checking the status of a service, starting or stopping a service, enabling or disabling a service at boot, and restarting a service.
Additional systemctl tips include viewing specific running services, checking for service unit files, and identifying failed services for troubleshooting.
Systemctl provides network engineers with command-line control over critical services, making troubleshooting and maintenance easier. Mastering systemctl also allows for automation of service startups after a reboot.
