I've run into some strangeness with the process package. When you kill some processes on the command line you correctly get a non-zero exit status. However when using the process package's terminateProcess (which sends a SIGTERM), it returns an ExitSuccess:
module Main (main) where import Control.Concurrent (threadDelay) import System.Process (createProcess, proc, getProcessExitCode, terminateProcess) main :: IO () main = do (_, _, _, ph) <- createProcess $ proc "/usr/bin/sleep" ["100"] terminateProcess ph threadDelay 1000000 print =<< getProcessExitCode ph -- prints Just ExitSuccess, should be Just (ExitFailure 143) term1: sleep 100 term2: pkill sleep term1: echo $? # 143 Anyone know what might be going on? -- Michael Xavier http://www.michaelxavier.net
