How to kill a child process by the parent process?

由 微笑、不失礼 提交于 2019-11-27 01:00:17
问题 I create a child process using a fork() . How can the parent process kill the child process if the child process cannot complete its execution within 30 seconds? I want to allow the child process to execute up to 30 seconds. If it takes more than 30 seconds, the parent process will kill it. Do you have any idea to do that? 回答1: Send a SIGTERM or a SIGKILL to it: http://en.wikipedia.org/wiki/SIGKILL http://en.wikipedia.org/wiki/SIGTERM SIGTERM is polite and lets the process clean up before it

问题 I need to do the following in Python. I want to spawn a process (subprocess module?), and: if the process ends normally, to continue exactly from the moment it terminates; if, otherwise, the process "gets stuck" and doesn't terminate within (say) one hour, to kill it and continue (possibly giving it another try, in a loop). What is the most elegant way to accomplish this? 回答1: The subprocess module will be your friend. Start the process to get a Popen object, then pass it to a function like

How to terminate process using VBScript

由 旧城冷巷雨未停 提交于 2019-11-26 22:59:04
问题 I have this VBScript code to terminate one process Const strComputer = "." Dim objWMIService, colProcessList Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2") Set colProcessList = objWMIService.ExecQuery("SELECT * FROM Win32_Process WHERE Name = 'Process.exe'") For Each objProcess in colProcessList objProcess.Terminate() Next It works fine with some processes, but when it comes to any process runs under SYSTEM, it can't stop it.

Linux C catching kill signal for graceful termination

由 天大地大妈咪最大 提交于 2019-11-26 22:54:18
问题 I have a process using sockets, database connections and the likes. It is basically a server process relaying between sensor data and a web interface, and as such it is important to ensure the application, if killed, terminates gracefully. How do I handle unexpected exceptions such as segfaults (at least for debugging) as well as kill signals so that I can close any connections and stop any threads running so that the process does not leave a mess of anything it is using? 回答1: You install

问题 I want to trap a signal send from Script-A.sh to Script-B.sh so in Script-A.sh i use the command: (Send SIGINT to Script-B.sh) kill -2 $PID_Script-B.sh And in Script-B.sh i catch the signal and call function Clean trap 'Clean' 2 It does not work, instead the Script-B.sh is killed right away without performing the Clean !! What i notice also is that if i want to send SIGINT from terminal to any script that traps it, a ctrl-c will be caught correctly, but not if i specify the signal via the

Service crashing and restarting

问题 There are several questions about it but I always read the same thing: "the service will be killed if the system need resources" or "you can't build an service that runs forever because the more it runs in background, more susceptible it is to the system kills it" and etc. The problem I'm facing is: My service runs fine and as it is expected, if I run my app then exit it my service is still running, but when I kill my app (by going to the "recent apps" and swype it away) the service stops.

问题 I need to write a program in c# that would just start, kill one process\exe that it is supposed to kill and end itself. The process I need to kill is another C# application so it is a local user process and I know the path to the exe . 回答1: First search all processes for the process you want to kill, than kill it. Process[] runningProcesses = Process.GetProcesses(); foreach (Process process in runningProcesses) { // now check the modules of the process foreach (ProcessModule module in process

How to kill all subprocesses of shell?

问题 I'm writing a bash script, which does several things. In the beginning it starts several monitor scripts, each of them runs some other tools. At the end of my main script, I would like to kill all things that were spawned from my shell. So, it might looks like this: #!/bin/bash some_monitor1.sh & some_monitor2.sh & some_monitor3.sh & do_some_work ... kill_subprocesses The thing is that most of these monitors spawn their own subprocesses, so doing (for example): killall some_monitor1.sh will

I'm trying to kill a process (specifically iChat). On the command line, I use these commands: ps -A | grep iChat Then: kill -9 PID However, I'm not exactly sure how to translate these commands over to Python. Assuming you're on a Unix-like platform (so that ps -A exists), >>> import subprocess, signal >>> p = subprocess.Popen(['ps', '-A'], stdout=subprocess.PIPE) >>> out, err = p.communicate() gives you ps -A 's output in the out variable (a string). You can break it down into lines and loop on them...: >>> for line in out.splitlines(): ... if 'iChat' in line: ... pid = int(line.split(None, 1)
