Re: [Haskell-cafe] Standard output of exec

      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-Pro...are 
some examples.

Dear All,
I have a program which invokes an external program via exec. I wish to 
capture the standard output of the program without using external 
(temporary) files.
