how do you make a script, then insert the coding into it via another Script?

Here is what im wanting to Put into a script through another script.

button.Click:connect(function()
    while wait(.7) do 
    for _, v in pairs (game.Players:GetChildren()) do 
        for _, p in pairs (v.Character:GetChildren()) do 
            if p:IsA("Part") and p.Name ~= "HumanoidRootPart" then 
                p.BrickColor = BrickColor.Random() 
for _, x in pairs(v.Character:GetChildren()) do


            if x:IsA("Shirt") and x.Name == "Shirt" then
        x:Destroy()

        for _, l in pairs(v.Character:GetChildren()) do

        if l:IsA("Pants") and l.Name == "Pants" then
            l:Destroy()

                end
            end
        end 
      end   
    end       
end
     end    end
    end)
