  java windows batch-file pid
  I need to know java process PID from Windows batch console.@echo off set p=%CD% FOR /F “tokens=1” %%A IN (‘”%JAVA_HOME%/bin/jps.exe -v”\|find “%p%”‘) DO SET str=%%A echo str = “%str%”Java process unique identifier is path from what it was executed. Script executes jps, that returns all java process information, for example9376 Jps -Denv.class.path=D:\tools\timesten\lib\ttjdbc6.jar; -Dapplication.home=C:\Program Files\Java\jdk1.6.0_24 -Xms8m 3856 -Dexe4j.semaphoreName=c:_program files (x86)_jet

  c linux pid fscanf ps
  I’m trying to display the details of each process, by redirecting the output of ‘ps’ command. I have redirected the ps output to a file. I’m reading from it and displaying the Pid and Command using fscanf. But I see that I get some lines duplicated, and in some cases a negative value for the Pids.void TR69_DM_GetProcDetails(char *FileName, int32_t *ProcCount, struct ProcessInfo *ProcVar) {char CharBuf[BUF_SIZE] ;int32_t i = 0;int Pid;char Cmd[100];FILE *FileDesc;FileDesc = fopen (FileName, “r”);

  background pid
  I was trying the following combination in order to get the pid of the ssh session (running in the background displays the pid) and than fg to get back to the ssh session and introduce the password: ssh targetHost &; fgI get the following error: -bash: syntax error near unexpected token `;’Why does the “;” not work to as expected in this case? My aim is to start a ssh session and know its pid and I need to do this in as few lines as possible. I need to start several ssh sessions, put them in

  java command-line pid
  I have Windows 7 32 bit with Java: How do I get the PID of a process by command line in Windows 7?I want to kill an application which I only can truly identify by the command line which ran it. We have several Java applications running on that machine. I need to stop specific ones. To be exact: I need to find tomcat which is run by catalina.bat. What do you think is the best way to do this?I know of tasklist, but it does not seem to be able to query the command line which started the process.

  bash pid env
  Any way to do this?I have a script that exports a few vars and runs a component.I’m looking to find out the actual values of some of these vars while the process is running. (Which applies here, because I’ll be incorporating those values into another script/program)The vars themselves are PID specific (I’m quite new at this, if that wasn’t obvious. Haha!)Thanks!

  java process pid
  This question already has an answer here:How to get PID of process Ive just started within java program?5 answersIf I get a process object in Java through Runtime.getRuntime().exec(…), or ProcessBuilder.start(), I can wait for it through Process.waitFor(), which is like Thread.join(), or I could kill it with Process.destroy(), which is like the deprecated Thread.stop().BUT: How do I find the pid of the Process Object? I don’t see a method for doing that in The Official Documentation. Can I do

  java profiling instrumentation pid
  Is there a way to find which jvms are currently running, and get their PIDs? e.g. when launching JVisualvm, it shows all local jvms. How can I do that? Background: I’m working on an instrumentation project, and I would like to attach an agent to another (unknown) java process. The idea is to display all currently running java processes, and let the user choose a process from that list. Thanks![edit] I do mean processes, not threads.

  linux pid lockfile
  I am using lockfile command in linux to manage access to a special file.When my principal script crashes for some reason, i finish having hanging locks that prevent any new launch of the principal script and bother heavily its execution.Is there a way to stock the PID of my lockfile processes so i can track them and make proper clean-up before relaunching my principal script.Hope i was clear enough…

  python linux restart pid
  I need to detect when a program crashes or is not running using python and restart it. I need a method that doesn’t necessarily rely on the python module being the parent process.I’m considering implementing a while loop that essentially does ps -ef | grep process nameand when the process isn’t found it starts another. Perhaps this isn’t the most efficient method. I’m new to python so possibly there is a python module that does this already.

In case of crash, I want to restart it. How can I keep track of all these process and periodically check if they are crashing or not?C

  java jvm jni signals pid
  Is there any possibility that I can directly send signal to a Java virtual machine which is created by calling JVM_CreateJavavm in native C/C++ code? e.g.:For a normal Java process, say its pid is 12345, I can send a signal 3 to it like this … kill -3 12345, and hopefully I could trigger javacore or heapdump by changing JVM configurations.However if the JVM is created thru JNI API and wrapped inside a C/C++ application, only the native process’s PID is visible, in that case if I send signal to

  centos proxy services squid pid
  Hey community,some days ago my squid crashed. I’m running squid 2.6 STABLE21 on CentOS. The output of the “show squid status” command is just squid dead but pid file existsstarting the service displayed an “OK” but trying to stop the squid failed. The weird thing is, that the squid service is not listed in the “Task-Manager”So I deleted the /var/run/squid.pid file and tried to restart the service, but I got the following message after executing the command:squid: ERROR: Could not send signal 0 t

  linux process pid
  What I want to know is PIDs that were assigned to a process before its last 2-3 restart.Scenario is after this particular process crashes, a log file is generated and PID of the process is concatenated to the name of log file. I have such 5 log files with name as hs_err_PIDs. I want to confirm whether these PIDs were assigned to the process I am concerned with, as I am little confused about it.Is there a way I can do it?

  linux process pid
  Many programs such as sshd create .pid files in /var/run/ that contain their process ID. Are these files reliable for determining whether a process is running? My guess is that these files are created manually by a process, and therefore will still remain in the file system if the program crashes.

  windows time process pid
  I’m looking for a way to automatically close a process with its pid in windows, after it has been “not responding” for a certain amount of time (should be configurable). I found many way to close process but none of them let you chose the amount of time it should wait before closing them. PS: The program causes an unhandled exception error box when it crashes which is not closed when the faulty process is, unfortunately the error message does not have its own process and cannot be terminated lik

  c linux process signals pid
  Is there any library which’s got some function the allows one to monitor an external process for events by its pid_t? I mean, monitor whether an external process has exited, or whether it has created one or more child processes (with fork), or whether it has become another executable image (via an exec or posix_spawn function family call) or whether a Unix signal was delivered to it.EDITI need something that does not interfere with the execution of the program that is being monitored. So, I’m no
