====== 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 file =====
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):

<code>$ ls -la
-rw-r--r--  1 pi pi   49.6M Dec 16 17:28 OnAirScreen_0.9.5_RaspberryPiOS.bin</code>

===== Make the script executable =====
To make the script executable, use the chmod command:

<code>chmod +x OnAirScreen_0.9.5_RaspberryPiOS.bin</code>
If you run //ls -la//, you'll see the file is now executable:

<code>$ ls -la
-rwxr-xr-x  1 pi pi   49.6M Dec 16 17:28 OnAirScreen_0.9.5_RaspberryPiOS.bin</code>
You'll now be able to execute the script successfully:

<code>$ ./OnAirScreen_0.9.5_RaspberryPiOS.bin</code>
