Re: getting output from shell commands

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:

Regards,

Olivier.

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
