Re: [Haskell-cafe] Execution of external command

so,

do (stdin,stdout,stderr,ph) <- runInteractiveCommand "script param" waitForProcess ph

when i should read stdout? before or after waitForProcess?

If you are sure that your script will behave nicely (or don't care if it doesn't), how about just: (_, h, _, _) <- runInteractiveCommand "script params" output <- hGetContents h -Yitz
