kill

问题 I'm running a script that daily downloads, builds and checks a program I'm contributing to. The "check" part implies performing a suit of test runs and comparing results with the reference. As long as the program finishes (with or without errors), everything is OK (I mean that I can handle that). But in some cases some test run is apparently stuck in an infinite loop and I have to kill it. This is quite inconvenient for a job that's supposed to run unattended. If this happens at some point,

问题 I have a bash script: #!/bin/sh for ((i=0; i<=10; i++)); do ssh "w$i" 'uptime;ps -elf|grep httpd|wc -l;free -m;mpstat' done & pid=$! sleep 3 kill -9 $pid I want to kill the ssh within the for loop , if it does not complete within 3 seconds. But my observations are, that the process is not killed and that the loop takes more than 3 seconds to kill. Can you please help me to correct my script so my script can kill the for loop process after 3 seconds? 来源： https://stackoverflow.com/questions

问题 I know that this question has been asked and answered many times and I know that the best way to end a thread is to use flags and exit the thread function when it is requested. This is also what I am doing at the moment, but my problem is that the thread function runs for a very Long time, so sometimes I need to wait for several hours until the thread ends. My thread function looks something like this: void threadfunction() { while(!exitRequested) { doSomeWork(); object1.doSomeWork(); object2

问题 This question already has answers here : Sending a POSIX signal from the JVM (2 answers) how can I kill a Linux process in java with SIGKILL Process.destroy() does SIGTERM (4 answers) Closed last year . A Script For Testing The script below just hangs until you press Ctrl + C , then it takes two seconds to shut down.

问题 Here is my shell script: #!/bin/bash PIDS=$(ps -e | grep $1 |grep -v grep| awk '{print $1}') kill -s SIGINT $PIDS echo "Done sendings signal" I am passing the name of the process as command line argument. The echo command is not getting executed, although the target processes are actually receiving the SIGINT signal and exited. Any suggestions? Update: I changed the code to: #!/bin/bash PIDS=$(ps -e |grep $1 | grep -v grep | awk '{print $1}'|grep -v $$) echo $PIDS kill -s SIGINT $PIDS echo

问题 I want to write a program, that should be notified by O.S. whenever any running process on that OS dies. I don't want to myself poll and compare everytime if a previously existing process has died. I want my program to be alerted by OS whenever a process termination happens. How do I go about it? Some sample code would be very helpful. PS: Looking for approaches in Java/C++. 回答1: Sounds like you want PsSetCreateProcessNotifyRoutine(). See this article to get started: http://www.codeproject

问题 I'm seeing a Java client application crash in the field, and I think it's because the server it's connecting to experienced a 12 second full GC pause. However, when I try to run the client / server locally out of Eclipse and reproduce the behavior using kill -STOP and kill -CONT to simulate a GC pause on the server, I'm not able to get the client application to crash--it just spins until I do kill -CONT. I'd like to figure out if the GC pause is actually the issue (if not I'll need to dive

问题 How can I kill a background process that was executed using a system function call in C language. Like for example I have a compiled application call "fooprocess".

问题 I use iptraf to monitor the network traffic in linux, and the shell command is(make iptraf running in background): iptraf -s eth0 -f -B -L ./traffic.dat if I want to get the result, I have to stop iptraf first, so I use the shell command: kill -SIGUSR2 $pid however, I could not stop iptraf if I move these shell commands into a bash script file(net.sh), and I get an error: kill: SIGUSR2: invalid signal specification I use 'kill -l' in the script file(net.sh), and I find there is no parameter

问题 My app runs a geolocalisation service that the user can active or disactive by a toggleButton. To check the status of the service, I write a boolean in the Shared Preferences. I listen the beginning of the service and the end of it thanks to the onDestroy() of my service. My problem is that: When the user kill the service with the "advanced task killer", I can't know that the service is killed, the onDestroy is not called ! How can I deal with that? Thanks for your help. Florent 回答1: When a
