It Started With a Hardware Limitation I have been using Quectel GNSS modules in my designs for a while. They are reliable, well-documented, and the support ecosystem is solid. But the module I had been using had one problem that I kept running into: no external antenna support . For most projects that is a minor inconvenience. For a marine vessel monitoring and control system , it is a non-starter. A vessel hull blocks sky view, antenna placement is critical, and the difference between a clean fix and no fix at all often comes down to whether you can mount the antenna where it actually has line of sight. An integrated antenna in a sealed enclosure below deck simply does not cut it. So I went directly to Quectel. The Conversation With Quectel I reached out through their official sample request channel. I was not expecting much — most component manufacturers have a standard process: fill out a form, wait, get a few uni...
If you want to run your own script for example a shell script, python etc as a Linux service, please follow this guide. I have tested and already using this methods and this works perfectly. In this example i am using an Ubuntu Linux and a shell script (which will run ngrok as service) if you want to know more about ngrok check out there website.
STEP#1: Prepare you script file that you want to run as a service.
once you are done with editing save and exit
STEP#2: Prepare the service
Go to "/etc/systemd/system" and create a file with your naming preferences but should end with a ".service" for example my file name was ngrok.service
This how the file should look like. ExecStart is where you define the script that you want to run. Once you done editing save the file and follow the commands as follows.
To enable the service
systemctl enable ngrok.service
Reload the deamon
systemctl daemon-reload
Test the service
if you run "service ngrok start" it will start the service and you can type "service ngrok status" to check if the service is running or not and you can top the service by "service ngrok stop" command.
if it is running it will show as above image.
