1-use concommand?

[Jaaay]

Is there a way to make a concommand ONLY be used ONCE by a SteamID?

so to say, you type in "hello" in console and it gives you a weapon, then you can't use that concommand again.

concommand.Add("hello",function(ply)
    if ply.hello then return end
    ply:Give("weapon_357")
    ply.hello = true
end)

    ply:Give("weapon_357")
    ply.hello = true
end)

That's not how it works...

Maybe

if ply.hello ~= nil then return end

My code is syntax-correct. He just said that for no reason
