Function execute 

pub fn execute(command: option<string>) -> (boolean, string, number)

Runs a shell command.

Parameters

• command: the command passed to the operating system shell. When absent, the function instead reports whether a shell is available.

Return value

A boolean that is true when the command terminated successfully, followed by the string "exit" (the command ended normally) or "signal" (it was terminated by a signal) and the return status. When called without a command, returns only a boolean indicating whether a shell is available.

Examples

print(os.execute("exit 0"))    --> true   exit   0
print(os.execute("exit 3"))    --> nil    exit   3
print(os.execute())            --> true   (a shell exists)
