Is there some shell script file inside /boot directory that gets called on system startup? Alternatively, is there any way to make such a script run by modifying only files inside /boot (like some config setting)?

The file /boot/armbian_first_run.txt is sourced by a bash script (/usr/lib/armbian/armbian-firstrun-config), but only if the file /root/.not_logged_in_yet exists.

Armbian still supports /etc/rc.local startup way:

 

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

YOUR_COMMAND

exit 0

 

i have installed a minimal Armbian OS on my s905 box with the intention of running a python3 program directly at startup. Since this program makes use of Tkinter i had to install an Xfse Desktop in order for Tkinter to function. I am able to run my python3 program from command line after the Desktop comes up.

 

I have included my python command namely:

python3 -m bCNC

 

as suggested above before the "exit 0" line in the rc.local file.

 

This did not appear to have any effect at all. the system just  boots to the Desktop. I actually am not interested at all in using this system for anything besides my program.

 

Can i have some advice on what I can do to get this to work?

Maybe so?

python3 -m bCNC &

 

Is the bCNC module visible in PYTHONPATH ?

@going,

 

since my last message I continued investigating and I have managed to get it to work. I had tried the "&" suggestion but that did not work in my case probably for the following reason.

 

bCNC uses graphics through Tkinter which in itself requires a GUI to be already invoked. It seems rc.local, and I also suspect crontab, are started before the GUI is invoked so I think this is why my program did not start. Of course it would have helped if I had been given some error message!

 

The solution was to create a .desktop file at ~/.config/autostart/ . The bCNC.desktop file needs to contain the EXEC line formatted as follows:

Exec=/usr/bin/python3 /home/xxx/.local/bin/bCNC

 

Note that the full path is required and, strangely, the "-m" option needs to be removed.

Well, you DID ask for a way to run a script, not a gui desktop application.

Glad you figured it out.

Did you check what that option does?

 

Quote

     -m module-name
             Searches sys.path for the named module and runs the  correspond‐
             ing  .py file as a script. This terminates the option list (fol‐
             lowing options are passed as arguments to the module).

 

And you removed the invocation of bCNC so, not that strange.
