Make OnAirScreen binary executable on RaspberryPi

This very short guide will show you how to make the OnAirScreen binary executable on your Raspberry Pi. This assumes your Pi is running Raspberry Pi OS or some other Linux/Unix-based operating system.

Navigate to the path of the directory where the file is:

$ cd ~/some/directory

You can confirm that the file is not executable by running ls -la, and observing there's no x (for executable):

$ ls -la
-rw-r--r--  1 pi pi   684 Dec 16 17:28 OnAirScreen_0.9.5_RaspberryPiOS.bin

To make the script executable, use the chmod command:

chmod +x OnAirScreen_0.9.5_RaspberryPiOS.bin

If you run ls -la, you'll see the file is now executable:

$ ls -la
-rwxr-xr-x  1 pi pi   684 Dec 16 17:28 OnAirScreen_0.9.5_RaspberryPiOS.bin

You'll now be able to execute the script successfully:

$ ./OnAirScreen_0.9.5_RaspberryPiOS.bin
