[Haskell-cafe] how to get a string from file

getItemFile :: IO String getItemFile test = do test <- readFile "input.txt" return test this is the program I did to take a file and get all the data from that file to a string. Can someone help me. I get this error Type error in explicitly typed binding *** Term : getItemFile *** Type : a -> IO [Char] *** Does not match : IO String What I need is to get the file to a string and then get it to a tuple by checking each places where the file contain a blank space Please help me Thanks
