How to List All Running Services Under Systemd in Linux

What is Systemd?

Systemd is a powerful init system in Linux that manages processes, services, and resources. Listing all running services is crucial for system administrators and users to monitor and manage system resources effectively. Here’s a step-by-step guide on how to list all running services under systemd in Linux.

1. Open Terminal:

• Launch your terminal emulator. This can be done using a keyboard shortcut (Ctrl + Alt + T) or by searching for “Terminal” in your system’s application menu.

2. Access Systemctl:

• In the terminal, use the systemctl command. This command is the primary tool for controlling the systemd system and service manager.

3. View Running Services:

• To list all running services, type the following command and press Enter:cssCopy codesystemctl list-units --type=service --state=running
• This command filters units of type service (--type=service) that are currently in a running state (--state=running).

4. Analyze the Output:

• The output will display a list of all running services, including their names, status, and other relevant information.

5. Additional Options:

• Explore additional options for more detailed information:
  • To view a concise list with only service names: systemctl list-units --type=service --state=running --no-pager --no-legend
  • For a detailed status of a specific service (replace your-service-name with the actual service name): systemctl status your-service-name

6. Filter by Specific Unit File:

• If you want to see services from a specific unit file (replace your-unit-file with the actual unit file name): systemctl list-units --type=service --state=running | grep your-unit-file

7. Check All Units:

• To list all units (including services, sockets, devices, etc.): systemctl list-units --type=unit --state=running

8. Explore Systemctl Commands:

• Familiarize yourself with other systemctl commands to start, stop, enable, or disable services as needed.
