How to execute lua bytecode generated by luac on linux

I have a simple lua hello.lua source code

print('Hello Lua')

I have executed this file for bytecode on a RedHat Linux machine using Lua5.3.4 like this:

luac -o hello.luac  hello.lua
chmod +x hello.luac
./hello.luac 
bash: ./hello.luac: cannot execute binary file

The architecture should be good, I think. I cannot figure out what is wrong.

Precompiled Lua programs run exactly like the source:



lua hello.luac

Since his answer @lhf says that Lua bytecode is executed using the Lua interpreter, and as manual suggests:

To allow Lua to be used as a script interpreter on Unix systems, a standalone interpreter skips the first line of a snippet if it starts with C #. Therefore, Lua scripts can be made into executable programs using the forms chmod +x

and #!

.



Add a shebang as the first line of your script:

#!/usr/bin/env lua
print('Hello Lua')
