Auto running a script


Create the script


Create a folder to store the script in 

mkdir ./bin
cd ./bin


Create the script using the nano text editor 

sudo nano script_auto_run


In the nano editor, type this script: 

#!/bin/bash
# Script to start our application
echo "Doing autorun script..."
sudo /home/pi/projects/my_project.a &
 

Replace "sudo /home/pi/projects/my_project.a &" with the commands you want carried out.  The "&" means do the command in the background. 

Note that when executing a command without logging is as a user you can't depend on any path or environment variables so you must provide full paths to everything. 

Save it by pressing Ctrl+X, " Y", ENTER 

This script needs to be made executable by typing this : 

sudo chmod 755 script_auto_run


  

You can test the script works by typing 

/home/pi/bin/script_auto_run


  

Setting it to be run


To launch the script at start-up edit the “rc.local” file needs to be edited. 

sudo nano /etc/rc.local


  

Add the following line: 

/home/pi/bin/script_auto_run


Save it by pressing Ctrl+X, " Y", ENTER 

Re-boot your RPi and it will run.
