I'm using Ubuntu Server 20.04 for Raspberry Pi 4, I'm trying to get a .sh file to run at boot, so I can just plug the Pi in and it runs the script, but how do I do that.

systemctl is what you're looking for. You'll need to install the script somewhere appropriate. Then, create a service file. Make sure that the file is executable (chmod +x /your/file.sh).

If that link makes you think you need "spark" it's just an example. Here's a [generic link] (https://linuxconfig.org/how-to-run-script-on-startup-on-ubuntu-20-04-focal-fossa-server-desktop) – So_about_that Dec 29 '20 at 23:22

You can do it via cron. Create a file (with any name you choose) in directory /etc/cron.d which contains the following:
@reboot root /path/to/your/file.sh
(the .sh file needs to be executable of course)

In most cases, you edit $ sudo nano /boot/config.txt and add what you need to start on boot, here is another way in more detailed explanation, copy and paste to new browser tab.
