TL;DR
To list all services in Ubuntu, you can try these four methods:
- Systemctl Command: List all services in a tabular format, including their status, unit name, and description.
- Service Command: List services along with their status, denoted by [ + ] for running services and [ – ] for stopped services.
- Init.d Directory: List services by examining the script files in the init.d directory.
- ls System Directory: List all systemd service unit files and related files in the

How to List All Services in Ubuntu
To list all services in Ubuntu, you have multiple methods at your disposal. The systemctl command in Ubuntu provides a straightforward and efficient way to retrieve a comprehensive list of services, their status, and additional details. The service command offers a simpler alternative, while the init.d directory allows for the manual examination of service files. Additionally, exploring the /etc/systemd/system directory unveils systemd service unit files and their configurations.
1. Systemctl Command
The systemctl command is a powerful tool for managing services in Ubuntu. It provides a straightforward and efficient way to list services, their status, and other details. Follow these steps:
- Open a Terminal in Ubuntu.
- Type the following command:
<strong>systemctl list-units --type=service</strong>- This command lists all services in a tabular format, including their status, unit name, and description.
- To filter services based on their status, you can use flags like –state=active,
--state=inactive, or –state=failed.
2. Service Command
Another method to list services in Ubuntu is by using the service command. Although systemctl is preferred, the service command can still be useful in certain situations. It offers a simpler way to list services and their statuses in Ubuntu. Here’s how you can do it:

<strong>service --status-all</strong>- This command provides a list of services along with their status, denoted by [ + ] for running services and [ – ] for stopped services.
- To list the details of a specific service, use the following command:
<strong>service service-name status</strong>Replace service-name with the name of the service you want to check.
3. Init.d Directory
The init.d directory contains script files responsible for managing services in Ubuntu. By examining this directory, you can list services and gain insights into their configuration. Follow these steps:
- Launch your Terminal window.
- Navigate to the
init.ddirectory by typing the following command:
<strong>cd /etc/init.d</strong>- Use the
lscommand to list all the files in the directory. - Each file in the
init.ddirectory corresponds to a service. You can view the details of a particular service by opening its respective file.
4. Using the ls System Directory
Another method to list all services in Ubuntu is by exploring the /etc/systemd/system directory. This directory contains systemd service unit files that define and configure various services on your system. Here’s how you can use this method:
- Open your command prompt and navigate to the
systemdsystem directory by typing the following command:
