![]() The above lines of code work for non-GUI programs. In case you want a script to run before you log in to your Raspberry Pi, this enables you to do so. Moreover, this also runs your program before Pi's X-Windows system starts, which means your program runs even before you log in to the system. By setting it to multi-user.target, you can establish a dependency relationship that will run the program when the system control is handed to the multi-user shell. WantedBy: It is the most common way of specifying the trigger for a unit. If you've changed your Pi’s name, you need to put that value for user. User: It identifies the name of your Raspberry Pi. So depending on what you want to execute, you need to add values for both these directives. ExecStart: It holds the absolute path and the program/script name that you want to execute at startup. For instance, if you want your program to execute after your Raspberry Pi connects to a network, you can use the network-online.target value. You can refer to Fedora's documentation on systemd to learn more about these values. ![]() Of course, you can change this value to suit your project requirements. However, it does not direct a dependency relationship for the service to trigger that's done through other directives such as Wants, Requires, and WantedBy. Setting it to network.target ensures that the listed value - network.target in this case - starts before beginning the current unit. After: It determines when to start the service. In the service file, paste the following lines of code: ĮxecStart=/usr/bin/python3 /home/pi/PiCounter/display.pyĪll your common configuration options fall under the Unit and Install sections, while the service-specific configuration options go under the Service section.Ī few of the above directive-value pairs you might need to modify include:.You can use any name for your service as long as it ends with the. In the CLI window, type sudo nano /lib/systemd/system/rvice.To set your program to run at startup, create a service unit file that will tell systemd which program to run and when. service unit files, which allow you to manage the startup behavior of programs and scripts on the system.īelow is a breakdown of the steps involved in launching a script/program at startup using systemd. For the purpose of this guide, though, we'll stick to. So, based on what kind of resource you want to declare, you need to choose a unit file type accordingly. ini files that hold encoding information about devices, services, sockets, start-up target, and other essential system components. The systemd method uses unit files, which are kind of like.
