I never used System.POSIX.Terminal myself but from what I read in the
haddock documentation I think this function can help you.
import System.Posix.Types (Fd)
import System.Posix.Terminal
disableEcho :: Fd -> IO ()
disableEcho fd = do
attribs <- getTerminalAttributes fd
setTerminalAttributes fd (withoutMode attribs EnableEcho) Immediately

Hello all,
I've written a little Haskell program to get information from a MySQL database (great thanks to anybody reading this who works on HSQL, by the way) but I want to keep the user's password concealed, obviously. Currently I prompt for it from the terminal, but the problem is that it's echoed just like all other input. I would like to disable input echo when asking for the password, but I'm not sure how. I notice there's a System.POSIX.Terminal module, but I have no idea how to use it, or whether it will do what I want. Any ideas would be greatly appreciated.
Best regards.
