Here’s what I use: @echo off rem there is a tab in the file at the end of the line below set tab= set cmd=javaw -jar lib\MyProg.jar set dir=%~dp0 echo Starting MyProg set pid=notfound for /F “usebackq tokens=1,2 delims=;=%tab% ” %%i in ( `wmic process call create “%cmd%”^, “%dir%”` ) do ( if /I %%i … Read more
There’s no such specifier. I think what you’re doing (casting the pid_t to long and printing it with “%ld”) is fine; you could use an even wider int type, but there’s no implementation where pid_t is bigger than long and probably never will be.
I think the simplest thing would be to open “/proc” and parse the contents. You’ll find the ppid as the 4th parameter of /proc/pid/stat In C, libproc has a get_proc_stats function for parsing that file: see Given a child PID how can you get the parent PID for an example.
This code is a simplified version of Yaqub’s code. I use this as a static method in a Util class: public static String getAppNameByPID(Context context, int pid){ ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE); for(RunningAppProcessInfo processInfo : manager.getRunningAppProcesses()){ if(processInfo.pid == pid){ return processInfo.processName; } } return “”; }
mshta terminates itself immediately. Maybe it’s too late to achieve parent process id by using WMI service. So, I’d use something like this to eliminate concurrent script processes. Generate random things. Determine an application which could be installed on each system, never terminates by itself (e.g. command prompt with /k parameter). Start the application in … Read more
This guy calls out to bash to get the PID. I’m not sure if there is an java solution to the problem. /** * Gets a string representing the pid of this program – Java VM */ public static String getPid() throws IOException,InterruptedException { Vector<String> commands=new Vector<String>(); commands.add(“/bin/bash”); commands.add(“-c”); commands.add(“echo $PPID”); ProcessBuilder pb=new ProcessBuilder(commands); Process … Read more
Another option: use a redirect to subshell. This changes the order in which background processes are started, so $! gives PID of the tail process. tail -f $1 > >(nc -l -p 9977) & wait $!
int numberOfTasks = 1; ActivityManager m = (ActivityManager)this.getSystemService(ACTIVITY_SERVICE); //Get some number of running tasks and grab the first one. getRunningTasks returns newest to oldest RunningTaskInfo task = m.getRunningTasks(numberOfTasks).get(0); //Build output String output = “the last application you’ve executed is ‘”+task.id+”‘ and the PID is ‘”+task.baseActivity.toShortString()+”‘”; getRunningTasks RunningTaskInfo
You have different option which you can use to receive exe names of currently running processes (process names like you wrote). The best way depends a little from the programming language which you use and from other requirements. For example you can use WMI. One other more old way is the usage of Performance Counters … Read more
Printed process ids < A.B.C > are composed of 6: A, the node number (0 is the local node, an arbitrary number for a remote node) B, the first 15 bits of the process number (an index into the process table) 7 C, bits 16-18 of the process number (the same process number as B) … Read more
