Run bash script on startup (Ubuntu-NanoPi)

you can execute a script when Nano Pi boots up.

You can add your script executable command to the bottom of .bashrc that will run your script every time open a terminal (or run a new instance of bash).

1. Make sure you are in the pi folder:

$ cd ~

2. Create a file and write a script to run in the file:

$ sudo nano run.sh

3. Save and exit: Ctrl+X, Y, Enter

4. Open up .bashrc for configuration:

$ sudo nano .bashrc

.bashrc is NOT intended to run scripts. It is run each time a non-login interactive shell is started and is used to configure the shell.
~/.bashrc: executed by bash(1) for non-login shells.

5. Scroll down to the bottom and add the line: ./run.sh

6. Save and exit: Ctrl+X, Y, Enter
