kill

I would like to repeatedly execute a subprocess as fast as possible. However, sometimes the process will take too long, so I want to kill it. I use signal.signal(...) like below: ppid=pipeexe.pid signal.signal(signal.SIGALRM, stop_handler) signal.alarm(1) ..... def stop_handler(signal, frame): print 'Stop test'+testdir+'for time out' if(pipeexe.poll()==None and hasattr(signal, "SIGKILL")): os.kill(ppid, signal.SIGKILL) return False but sometime this code will try to stop the next round from executing. Stop test/home/lu/workspace/152/treefit/test2for time out /bin/sh: /home/lu/workspace/153

Basically, what signal does '0' represent, because here I see SIGNAL numbers starting from 1. dwalter sending the signal 0 to a given PID just checks if any process with the given PID is running and you have the permission to send a signal to it. For more information see the following manpages: kill(1) $ man 1 kill ... If sig is 0, then no signal is sent, but error checking is still performed. ... kill(2) $ man 2 kill ... If sig is 0, then no signal is sent, but error checking is still performed; this can be used to check for the existence of a process ID or process group ID. ... This is a

Say I want to kill every process containing the word amarok. I can print out the commands I want to execute. But how do I actually make the shell execute them. ie. ps aux | grep -ie amarok | awk '{print "kill -9 " $2}' Output: kill -9 3052 kill -9 3071 kill -9 3076 kill -9 3077 kill -9 3079 kill -9 3080 kill -9 3082 kill -9 3083 kill -9 3084 kill -9 3085 kill -9 3086 kill -9 3087 kill -9 3088 kill -9 3089 kill -9 4031 From man 1 pkill -f The pattern is normally only matched against the process name. When -f is set, the full command line is used. Which means, for example, if we see these lines

I am looking for a Java tool/package/library that will allow me to force-kill a child process. This tool/package/library must work on Windows platform (mandatory). Support for Linux/Unix is desired. My Problem My Java code creates a child process that will simply not react to the standard Java way for killing a child process: process.destroy(), and, since I do not have the child's source code, I cannot program it to better handle termination requests. I have tried closing the child process' error input and output stream before calling destroy(), and for no effect. I have even tried passing

I got an Activity that when it starts, it loads an image from the internet. In an effort to save memory, when the Activity is left by the back button being pressed, I want the activity to dump all data, that is get rid of all the strings and images that are in it. I figured the best way to do this was to just kill the activity. Well, I can't seem to figure out the callback for when the Back button is pressed. So, I have been trying to use the onPause() and the onStop() callbacks for the task but both ways force close my app. Here is the code: public void onPause() { this.finish(); } public
