How about

import List(sort)

main = do
    fileContents <- readFile "inputFile"
    -- the do notation hides the bind (>>=) operator.
    -- fileContents :: String (=== [Char])
    let l = lines fileContents
    -- l :: [String]
    let sortedL = sort l
    -- sortedL :: [String]
    let outputData = unlines sortedL
    -- outputData :: String
    putStr outputData
