[Haskell-cafe] Standard output of exec

[Daniel Díaz]

You can also use my process-streaming 
<http://hackage.haskell.org/package/process-streaming> library:

   import System.Process.Streaming
   import qualified Pipes.ByteString as B
 
   -- collects stdout as a lazy ByteString
   execute (pipeo (fromFold B.toLazyM)) (shell "echo test")

It depends on the pipes ecosystem and some other stuff, however.

Here 
<http://hackage.haskell.org/package/process-streaming-0.6.5.0/docs/System-Process-Streaming-Tutorial.html>are 
some examples.
