# Set a default log file location if the parameter was empty, i.e. # Store first parameter in a variable, which should be the log file location. I created the following shell script, which I named testscript.sh: #!/bin/bash To explain the steps involved with configuring Systemd for starting up a script each time you boot your Raspberry PI, we would need a script for testing purposes. As such it makes Systemd the perfect tool for configuring a script to execute each time you startup your Raspberry PI. Think of automatically restarting processes, when they failed and running periodic tasks.Īfter reading this brief Systemd introduction, you can imagine that Systemd is a key component in Linux. This includes for example the mounting of the file systems, setting up networking and getting the display manager up-and-running.īesides managing the system initialization, Systemd also provides a services manager that assists with keeping your Linux system running. Systemd is the one that starts all the key processes to get your Linux system properly running. What is this funky Systemd thing I just mentioned? Well, in Linux and therefore also on the Raspberry PI, the so called Systemd software manages the initialization of the system during system startup. A previously published article provides detailed instructions for setting up your Raspberry PI as a headless server. ![]() If you do not have these extra parts available, you could setup your Raspberry PI as a headless server instead. This means that I also needed a monitor, monitor cable, keyboard and mouse. Throughout this article, I’ll use my Raspberry PI 4 with a freshly installed Raspberry PI operating system, including graphical desktop environment. In addition to the Raspberry PI hardware itself, you would need a suitable power supply and a micro-SD card where you already installed the Raspberry PI operating system. It can be a small Raspberry PI Zero or a more powerful one, such as the Raspberry PI 4. To complete the examples described in this article, you need an operational Raspberry PI. ![]() For example a Python program or your own compiled C/C++ program. ![]() Note that when I write script, I do not just mean a shell script, but basically any sort of program. I’ll explain step-by-step how you can automatically startup a script on your Raspberry PI using Systemd. This article aims to answer exactly this question. Once done, you want to automatically start your newly developed Python program each time you power up your Raspberry PI. Based on the user input, the GPIO ports need to be controlled. You typically have a basic web interface for obtaining user input. Take for example a home automation solution. When developing a Raspberry PI based solution, this often involves the development, configuration and/or customization of software programs. ![]() This article contains detailed instructions on how you configure a script or program using Systemd to automatically startup each time you power up your Raspberry PI. Developing your own program for a Raspberry PI, which you want to automatically start each time your Raspberry PI boots? Not sure how to do this? Well, you came to the right place.
