Hi, I would like to be able to run a shell command like curl and process the output in my Haskell program, but I couldn't find anything helpful about it. Something like main = do args <- getArgs inp <- exec "curl" args putStrLn (processInput inp) would be very helpful. Regards Philip
Hello,
I would like to be able to run a shell command like curl and process the
output in my Haskell program, but I couldn't find anything helpful about it.
Try looking in System.Process. runInteractiveProcess should work for you. -Jeff --- This e-mail may contain confidential and/or privileged information.

Hi Philip,
I just asked a question to the list about using runInteractiveCommand. You
may find the code useful but will need to either remove the forkIO
instruction or synchronize the two threads using a MVar to avoid the
concurrency problem I had.
You'll find the thread here:

Olivier.
