systemctl

Systemctl is a command-line tool used on Linux systems to control and manage system services and processes. Think of it as a control panel to start, stop, restart, enable, or disable services like web servers, databases, or network managers. It communicates with the system's init system (systemd) to manage how and when services run, ensuring the system operates smoothly. Systemctl helps administrators automate tasks, troubleshoot issues, and configure system behavior efficiently by providing a consistent interface for managing the system's components.
