[lua]Read a file to a variable

I am making some software for a lockable door for my server, and i want it configurable. So i want the user to be able to put the password in a file called "pass", and then read the contents to a variable and compare to input from the person who wants to log in. How do i do that?

Like this

local file = io.read("filename", "r") -- open file in read only
contents = file:read()
file:close()

while true do
write "Enter Password: "
local input = read("*")
if input == contents then
  print "correct password"
  doStuff()
  break
else
  print "invalid entry"
end
end

<name> Expected at file:read()

Try changing the io.read call to an io.open call. And make sure the file isn't blank.

Ya my bad, it should be:
local file = io.open("filename", "r")
