![]() sleep provides additional time for all system resources to get started (e.g. Sleep and the redirect are often useful in running cron jobs. any output or errors ( stdout or stderr, 2>&1) from your program are re-directed ( >) to a file: /home/pi/logmyprogram.txt.your program (assumed to be /home/pi/MyPythonProgram.py) is started.sleep 20 waits 20 seconds after cron is started before it starts your program.simply instructs cron to execute the following commands each time the system boots.Move the "insertion point" in nano just below any existing text in crontab, and type the following: (sleep 20 /home/pi/MyPythonProgram.py) > /home/pi/logmyprogram.txt 2>&1 "Schedule" your program to start each time the RPi boots: ![]() Your default crontab will open in the nano editor. Your program must be marked as executable you can ensure the program is executable with this command: $ chmod a+x /home/pi/MyPythonProgram.pyĪt the bash prompt ( $ ), open your crontab for editing (choose nano as your default editor if asked): $ crontab -e You must know the location of your program - full path specification e.g. You will see a prompt similar to the one shown below indicating where to begin your $ Once you are logged in as default user pi, you are presented with a terminal screen in the bash shell. Use the terminal (via SSH if necessary) and Command Line Interface (CLI) as follows: 1. You can use cron to start a Python program upon startup - this is very simple. You don't have to do anything to the RPi to have it start (boot) when power is connected - this is the way it works! My question is: How do I configure the pi so that i can plug it back in, it boots up itself and runs the program without having to use ssh or a keyboard and monitor to login.
