This article will guide you through the basics so that you can start, stop, or restart services depending on what you need.
In Linux, the most common way to manage services is through the systemd system, which controls services on modern Linux distributions.

Why Do You Need to Start, Stop, or Restart Services?
- Starting a Service: You may need to start a service after installing software or when the system boots up without automatically starting certain services.
- Stopping a Service: Stopping a service can free up system resources or prevent unwanted programs from running.
- Restarting a Service: If a service is malfunctioning or after making configuration changes, restarting is often the quickest way to resolve issues.
