raspberry pi how to make a program run at startup

You should see something that looks like this : To edit it we use the command : sudo crontab -eĮach user of the system (ie “pi”) can have its own Crontab but in this case we want to add it as an admin so we prefix our “crontab -e” command with “sudo”. This is a table that contains the list of jobs that Cron will monitor and run according to it’s details.

To create a new job to Cron we will modify the “crontab”. Once you are running at boot it isn’t so easy to debug so don’t rush! Step 2 – Add A New Cron Job Make sure your script works and does what you expect it to. This should show the contents of your script. In this example I will assume the script is called “MyScript.py” and it is located in “/home/pi/”.ĭouble check you’ve got the correct path by typing : cat /home/pi/MyScript.py It is important to remember its name and location. This will be the script that will run at boot time. The first step is creating your Python script. You can use it to run commands or in this case, a Python script. It is a very powerful tool and useful in lots of situations. There are a number of different techniques to do this but I prefer the method that uses “cron”.Ĭron is a job scheduler that allows the system to perform tasks at defined times or intervals. There maybe times when you want to run a Python script when your Raspberry Pi boots up.
