Discuss Lua's operating system facilities and provide an example that demonstrates how to execute a system command from within a Lua program.

Lua provides operating system facilities that allow you to interact with the underlying operating system, execute system commands, and perform various system-related tasks. These facilities enable you to integrate Lua seamlessly with the operating system environment. Here's an in-depth explanation of Lua's operating system facilities and an example of executing a system command from within a Lua program: Lua's operating system facilities are primarily provided through the `os` library, which contains functions and constants related to system operations. 1. System Command Execution: Lua allows you to execute system commands using the `os.execute()` function. This function takes a string argument representing the command to be executed and returns the exit status of the command execution. Example: ``` lua`local command = "ls -l" -- Execute the system command....
