Helped me; might help others. If it works in the command tab and not as a cron job, it might be trying to run before dependencies are available. You can give the pi time to first fully boot by delaying the script to run 30 seconds later as follows: @reboot sleep30; python3 home/pi/Desktop/…etc
The solution is to run a terminal with the command to run code steps :- . Make sure script is executible chmod +x /home/pi/your program.py .Open crontab. -e crontab -e . Entre command @reboot lxterminal -e /usr/bin/python3 /home/pi/your_program.py And use (&) in if code is not running with above command thank U .
Those who are wondering how to undo this : Open crontab: crontab -e (or sudo crontab -e if you used sudo initially) Find the entry: Look for the line you added earlier, which starts with @reboot. Delete the entry: Remove the entire line by pressing dd (or use the delete key). Save and exit: Save the changes and exit the editor.
This is good, its an easy way of doing it.! however, making daemons is the way to go when you need to ensure a program that crashes can re-open automatically.
for those where crontab didnt do anything, in nano editor, try pressing ctrl+T and then execute the python code and if you have any error, once the code runs without any error in nano editor, delete the generated lines and sudo shutdown -h now, switchoff and then on Peace Out!
Excellent! Short and to the point. I did "crontab -e" without the sudo, because the system seems to boot into my user name. Not sure about this. Thanks again.
with this, does the pi also not need to be able to log in automatically with the username and password? How can it run the code without logging in first?
I activated the code and it worked, my servo would spin but the whole program only ran for a few seconds before stopping, how do i make it run continuosly until the power is cut?
If you are running the script with root priveleges you dont, but if you dont those commands will just not go through because the permission gets denied.
Hey. How do I get it to boot up where I left off at? I’m using it to monitor my vehicles gauges and have made adjustments but when I power down ot doesn’t start where I left off and have to make those adjustments again.

Hey is it possible to call to run multiple files at the same time on startup and/or would it be as simple as another line imitating what is shown for the second python file to run?

Hi thank you for the video, I want to run an executable, in this case its Universal Gcode Sender (an application for CNC machines) but it wont boot on start up, there was no error messages displayed, do you know what could be the problem?
if I type: "python3 main.py" it runs But if I type the entire path: "python3 /home/pi/main.py" it won't run.. and I get: "can't open file: [Errno 2] No such file or directory" Anyone had my same problem? How can I fix this? Thanks
Open your terminal and try typing "ls /home". This lists the files in the "home" directory. Do you see "pi" in the output? Next type "ls /home/pi". What files do you see? Do you see "main.py"? If not, then main.py is in a different place
Hey thanks what if I want to run two scripts for example a python and a pure data one? I tried putting both in @reboot on crontab but it did not work for the second.
You have to separate the commands with semi-colons. If that doesn't work then there's something wrong with your other command. Try running the command in your terminal and see if it works before trying it in crontab
You should have made the video a little more complex like adding two or more scripts to run at startup. Because that's what im trying to figure out how to do right nw
