local tArgs = {...}
local databaseFile = fs.open(".database", "a")
if #tArgs >= 4 or #tArgs < 3 then
error(..shell.getRunningProgram()": 3 args expected - username, id, password")
end
databaseFile.writeLine(tArgs[1]..","..tArgs[2]..","..tArgs[3])

I dont understand how to make a database file though…..

local yourDatabase = {
  ["somename"] = "somepass",
  ["somename2"] = "somepass",
}

local function saveDatabase()
  local handle = fs.open(".database", "w")
  handle.write( textutils.serialize( yourDatabase ) )
  handle.close()
end

local function loadDatabase()
  local handle = fs.open(".database", "w")
  local contents = handle.readAll()
  handle.close()
  yourDatabase = textutils.unserialize( contents or "{}" )
end

local function addToDatabase(user, pass)
  if yourDatabase[user] then
    print("This user exists")
  else
    yourDatabase[user] = pass
  end
end


local function removeFromDatabase(user, pass)
  if not yourDatabase[user] then
    print("This user does not exist")
  else
    yourDatabase[user] = nil
  end
end
