How to List All Services in Linux
In the world of Linux, services are crucial components that run in the background, enabling various functionalities and ensuring the smooth operation of the system. Whether you are a beginner or an experienced user, knowing how to list all services in Linux can be incredibly beneficial. This article will guide you through the process of listing all services in Linux using different commands and tools.
Using the `systemctl` Command
The `systemctl` command is a versatile tool that allows you to manage services in Linux. To list all services, you can use the following command:
“`
sudo systemctl list-unit-files –type=service
“`
This command will display a comprehensive list of all services available on your system. The `–type=service` option ensures that only service units are shown in the output.
Using the `service` Command
Another way to list all services in Linux is by using the `service` command. Although this command is less commonly used than `systemctl`, it can still be helpful in certain scenarios. To list all services, execute the following command:
“`
sudo service –status-all
“`
This command will provide a detailed status of all services, including their current state and whether they are running or stopped.
Using the `systemctl` Command with Filters
The `systemctl` command also allows you to filter the output based on specific criteria. For example, if you want to list only the active services, you can use the following command:
“`
sudo systemctl list-units –type=service –state=running
“`
This command will display a list of all services that are currently running on your system.
Using the `grep` Command
The `grep` command is a powerful tool that can be used to search for specific patterns in text. To list all services containing a particular keyword, you can use the following command:
“`
sudo systemctl list-unit-files –type=service | grep “keyword”
“`
Replace “keyword” with the term you want to search for. This command will display all services that contain the specified keyword in their names.
Conclusion
Listing all services in Linux is an essential skill for anyone working with Linux systems. By using the `systemctl` and `service` commands, you can easily view the available services and their states. Additionally, by applying filters and using tools like `grep`, you can refine your search and find specific services based on your requirements. Whether you are troubleshooting an issue or exploring the capabilities of your Linux system, knowing how to list all services will undoubtedly prove to be a valuable asset.
