simple and compact key system

hello I created a key system a long time ago using the roblox console. You can modify as you wish, add commands if necessary and ask me for help if necessary.
My discord --> OuiSom89#7276

function p(txt)-- function "p" which will write "[CONSOLE] >> " to each message written by the console
    rconsoleprint("\n[CONSOLE] >> "..txt)
end

function incorrect_commande()
p("incorrect command try again")
imputted_commande()
end

function imputted_commande()

    local inputted_commande_function = rconsoleinput()
    
    if inputted_commande_function == "OuiSom89"then
        p("correct key. Thanks for using this script.\n[CONSOLE] >> The key is correct, if you used krnl I invite you to do the \"Close\" command Otherwise I invite you to minimize the console. --> ")
        writefile("key_sys", "OuiSom89")
        imputted_commande()
    elseif inputted_commande_function == "Close" then
        rconsoleclear()-- clear console
        rconsoleclose()-- close the console only with krnl synapse does not have this functionality for the other exploits I don't care
    elseif inputted_commande_function == "Restart" then
        Start()-- reboot script
    elseif inputted_commande_function == "Discord" then
        setclipboard("discord.gg/W7VHxeP4ks")
        p("The discord link is copied to your clipboard. --> ")
        imputted_commande()
    elseif inputted_commande_function == "Key_Link" then
        setclipboard("https://link-target.net/443009/key-on-dark-script-lua")
        p("The key link is copied to your clipboard. --> ")
        imputted_commande()
    else p("incorrect command try again. --> ")
        imputted_commande() 
    end
end
function Start()-- The script is made using functions to be able to start again at any time
    rconsolename("key system")-- change console name
    rconsoleclear()-- clear console
    p("Hello, before proceeding to the verification of the key I give you the commands of the bot which could be useful to you.\n[CONSOLE] >> Command : Close(only with krnl), Restart, Discord, Key_Link.\n[CONSOLE] >> I will check if you have used this script before.\n[CONSOLE] >> Wait 1second.")
    wait(1)
    if isfile("key_system") == true then--function that returns true if the "key_systel" file is present
        p("The key is correct, if you used krnl I invite you to do the command \"Close\" and other if necessary, otherwise I invite you to minimize the console. --> ")
        imputted_commande()--redirect to function above
    else p("I don't see any trace of you using this script I invite you to use the Key_Link command to have the link of the key which will be copied into your clipboard. --> ")
        imputted_commande()
    end
end
Start()
