How to Check Services Running in Linux

Different operations are running in the background of Ubuntu and are not visible to the users. These services run for specific purposes and can only be managed by some utilities. One of these utilities is “systemctl” to start/stop services. These services make the processing unit of the computer busy, which consumes the battery health as well as slows down other programs.

Considering the importance of services, this post will provide the methods to check services on Linux. The outcomes of this article are:

Method 1: How to Check Services Running in Linux Using “systemctl” Utility?

As discussed earlier, the “systemctl‘ utility is the most used to manage the services on Linux-based systems. Let’s see how it can be used to list down services:

List Down Machine Services

Top 10 Linux Distros

First of all, we are supposed to list down all the machine services using the systemctl command:

$ systemctl list-units --type=service --all

There are different states of the services, these can be loaded, running, or not found.

Check Running Services

To display all the running services, use the command:

$ systemctl list-units --type=service --state=running

All the services in a running state will be displayed on the screen.

List Down the Loaded Services

Similarly, to display all the loaded services, simply use the command:

$ systemctl list-units --type=service

Show the Enabled Services

Likewise, to display the enabled services, use the command:

$ systemctl list-unit-files --state=enabled

List Down Disabled Services

To display the disabled services, change the state in the above command:

$ systemctl list-unit-files --state=disabled

These are the different commands that can be used to display the status of the services using the systemctl utility.

Method 2: How to Check Services Running on Linux Using “service” Command?

Apart from the “systemctl” utility, another utility named “service” can also provide the list of services running in Linux.

List Down All Services

The following “service” command will list down all the services on the Linux system:

$ service  --status-all

In the above figure, the services with the “+” sign are running on the system where the services with the “-” sign are not running on the system.

Check Running Services

To list down only the running services, use the command:

$ service --status-all | grep '\[ + \]'

Check Only Stopped Services

Likewise, to display the services which are not running but are installed on the system, use the command:

$ service --status-all | grep '\[ - \]'

In these ways, the running services can be checked on Ubuntu.

That’s all from this guide!

Conclusion

To check the services running on Linux, open the terminal and run the command “systemctl list-units –type=service –state=running”. The service command “service –status-all | grep ‘\[ + \]’” can also list all the running services on Linux. Apart from the running services, the “systemctl” utility and “service” command can also be used to list the stopped or all services. This post has provided all the possible commands to check services running in Linux.
