Here's an alternative:

module Main where

(snip john's version)

And what list would be complete without a points-free version. It doesn't operate on stdin, though like John's does:

pointsFreeCat :: IO () pointsFreeCat = getArgs >>= mapM readFile >>= putStrLn . concat

-- And a regular version for reference

cat2 :: IO () cat2 = do a <- getArgs lines <- mapM readFile a putStrLn $ concat lines

peace,

You probably want `putStr` instead of `putStrLn`, as the latter introduces a gratuitous newline at the end of the concatenated contents. Dean
