systemd is a software suite that's present on many Linux distributions. It's not quite ubiquitous, but it's a staple on the most popular distros, including Debian, Ubuntu, Fedora, Manjaro and Arch, and more.
What it's best known for is having the ability to control processes running on a system. Using systemd, you can start or stop any service installed on Linux. It's also an easy tool to list information about the services, such as if they are running, if they start automatically at boot up, etc. In this guide, we'll show how to use systemd (specifically the systemctl command) to a see a list of services on Linux.
