What is Systemctl?

The primary command for managing systemd services, including starting, stopping, enabling, and checking service status.

Systemctl controls the systemd service manager. Key commands: systemctl start/stop/restart service (manage service), systemctl enable/disable service (auto-start at boot), systemctl status service (check status and recent logs).

Other useful commands include systemctl list-units (active units), systemctl list-unit-files (all units), systemctl daemon-reload (reload after config changes), and systemctl is-active service (quick status check for scripts).
