cd /home/pi/Desktop /bin/bash /home/pi/Desktop/myfile& /bin/python3 /home/pi/Desktop/myfile.py& rc.local is not the best way to do things now however as rc.local runs as root - then you don't need sudo and the best way is full paths to everything then use & to mean run in the background make sure y...

I would like when the raspberry starts up that it is checked whether there is a connection to the internet. true: a code must be executed to get the time off the internet. false: wait until there is a connection and then execute the code to retrieve the time from the internet Well that's a complete...

You have not explained how you want to run your python program ? but assuming you just want to double click on the file name in the file manager, first you need to make sure your program has this as the first line #!/usr/bin/env python3 then you need to make the file executable chmod 740 filename n...

Are you wanting your python code to run at pi boot ? if so you need to use the " /etc/xdg/lxsession/LXDE-pi/autostart " file to run the terminal and your python program after the GUI has loaded. so open the file with the following command sudo nano /etc/xdg/lxsession/LXDE-pi/autostart and add as th...

Not sure what you mean by “activate a code”.

Can you elaborate?

when i start up my raspberry it has to connect to wifi. when connected, a code must be executed in the terminal.
if it is not connected, the code must not be executed

rodink

I would like to execute a code in the terminal when I start up my raspberry when it is connected to the internet.
anyone have an idea how I could do this?

So if you want to set the date/time from google you need this line sudo date -s "$(wget -qSO- --max-redirect=0 google.com 2>&1 | grep Date: | cut -d' ' -f5-8)Z" to run it from cron on reboot you would need to do it like this use sudo crontab -e to edit the root cron file as setting the date needs r...

but this does not update the time automatic when i start the raspberry pi

rodink

ik heb het bestand 2018-06-27 respian-stretch gedownload.
helaas past hij niet automatisch de tijd aan terwijl ik dit wel wil hebben.
weet iemand een andere oplossing hiervoor?

rodink

unfortunately this does not work for me.
now i get 1:00 am when i start up the raspberry.
I have also tried a lot with the NTP stuff.
unfortunately this did not help.

hi,
ik wil graag de tijd aanpassen naar de actuele tijd op internet. ik heb een code gevonden die de tijd aanpast aan de google.com tijd.
sudo date -s "$(wget -qSO- --max-redirect=0 google.com 2>&1 | grep Date: | cut -d' ' -f5-8)Z"
maar hoe kan je deze code activeren als je je raspberry opstart?

rodink

Hi,
I would like to adjust the time to the current time on the internet. I found a code that adjusts the time to the google.com time.
sudo date -s "$(wget -qSO- --max-redirect=0 google.com 2>&1 | grep Date: | cut -d' ' -f5-8)Z"
but how can you activate this code when you start your raspberry?
