How do I clear the console in a Lua Program

I'm making my first Lua program with the console, and I need to find out how to remove all the text in the console without just appending a ton of \n's.

Sorry for the late answer, but if anyone check this post here's a way to do it :

if not os.execute("clear") then
    os.execute("cls")
elseif not os.execute("cls") then
    for i = 1,25 do
        print("\n\n")
    end
end

This will work on any os.

As mentioned in the other reply, you can use os.execute() to clear the console. However, if you do not have access to this function, then you might be forced to spam the console with new lines, so it seems "empty" to the user.

However, if you are able to use os.execute, then you should definitely use it.

for i = 1, 255 do
    print()
end

If your console understands ANSI terminal escape sequences, try io.write("\027[H\027[2J").

You can use os.execute().

On Windows:

os.execute("cls")

On Unix:

os.execute("clear")
