Now that we have a script, and we know it’s working correctly, let’s create a new systemd service. Now remove the file that was created by your script. Let’s run the program to check if it’s working correctly (it should!): $ lsĭesktop Documents Downloads ensure-file-exists.py MagPi Music Pictures Public Templates Videosĭesktop Documents Downloads ensure-file-exists.py MagPi Music Pictures Public required_file Templates Videos Note that by using with, we don’t need to write the code to close the file. If the file doesn’t exist, it will be created. We just create a file with the write mode, and write “OK” inside. With open("/home/pi/required_file", "w") as f: Here’s the content of the script: #!/usr/bin/env python3 Now, edit the file with whatever text editor you prefer (Nano, Vim, Emacs, etc). In your home directory, create a Python file and make it executable. Let’s say we want to make sure a given file exists when we boot the Raspberry Pi 4. Note that I’ll use “/home/pi” as the home repository during all the tutorial, so you’ll have to replace “pi” with your username if you changed it from the default one. Let’s create a simple Python program in your home repository. To be able to start a program, you first need to have one.

Watch this video as an additional resource to this article: Note: this also works for Raspberry Pi 3 boards. In this tutorial I’ll show you step by step how to use systemd to make your Raspberry Pi 4 program start on boot. Good news, it’s already installed for you if you use Raspbian/Noobs/Ubuntu for RPi. Systemd is simply a standard Linux process to control which program should start when the operating system boots. How could you make your Raspberry Pi 4 program start on boot?įortunately, there are some solutions to your problem. But here’s the problem: to start it you always have to power on the board, log in (with a screen and keyboard or via ssh), and start your program. Let’s say you have developed a super program running on your Raspberry Pi 4 board.
