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.
Solving Issues
rc.local runs as root user which might cause problems for some actions you perform in scripts. You may also want a slight delay before a script is executed. There's solutions to both of these issues here.

tip if you don’t already know know…
export PATH=$PATH:/home/pi/bin
this will add the created bin directory to the existing path for compilation

Running 2016-5-10 Raspian on Raspberry Pi 3 and find that /etc/rc.local does not run on bootup.
here is a copy of my rc.local file. Neither the IP address print routing nor my play_tcp are run on bootup.
“#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will “exit 0” on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
# Print the IP address
sudo /usr/local/bin/play_tcp -a 192.168.0.115 &
_IP=$(hostname -I) || true
if [ “$_IP” ]; then
printf “My IP address is %sn” “$_IP”
fi
exit 0
”
Anyone know why it doesn’t execute? If I type /etc/rc.local it runs both parts, but it won’t run automatically on reboot.
