terminate

This has been asked before but I can't find a definitive answer, in code. I open a process, ProcessA (with PID 1234). This process opens a child process, ProcessAB (PID 5678). After I'm done I terminate ProcessA but I still have the lingering of ProcessAB. How do I terminate the whole process tree? What I mean, how do I make sure that if I terminate the process I opened I am also terminating all the associated processes? Thanks Code is appreciated. Mike Marshall Check this thread for grouping processes within a "job". If that does not work for you, a home grown approach might go as follows:

How do you terminate a run in SBT without exiting? I'm trying CTRL+C but it exits SBT. Is there a way to only exit the running application while keeping SBT open? Seth Tisue In the default configuration, your runs happen in the same JVM that sbt is running, so you can't easily kill them separately. If you do your run in a separate, forked JVM, as described at Forking , then you can kill that JVM (by any means your operating system offers) without affecting sbt's JVM: fork in run := true From sbt version 0.13.5 you can add to your build.sbt cancelable in Global := true It is defined as "Enables

I am learning how to use threads in Java. And I wrote a class that implements Runnable to run concurrently to another thread. The main thread handles listening to the serial port where as the second thread will handle sending data to that same port. public class MyNewThread implements Runnable { Thread t; MyNewThread() { t = new Thread (this, "Data Thread"); t.start(); } public void run() { // New Thread code here } There first thread starts the second like this: public class Main { public static void main(String[] args) throws Exception{ new MyNewThread(); // First thread code there } } This
