The function System.system (:: String -> IO ExitCode) makes the OS

standard output and standard error.
How do I easily capture this output?
Try System.Process.runInteractiveCommand:
import System.Process
import System.IO
main = do
(inH, outH, errH, _) <- runInteractiveCommand "wc -w"
hPutStr inH "foo bar baz"
ws <- hGetContents outH
putStrLn ws
-- Prints 3
