How do I get an accurate list of running processes in Linux from a Java application? -


i'm making application , 1 of requirements @ moment able search processes of other running applications , kill them if needed.

i have tried "jps" comes jdk , need. process id of application, , real name of application. using can kill process id, match name processes need terminate, without terminating wrong processes. unfortunately not of end-users of application have jdk jps not reliable. need way this.

i have tried many "ps" commands don't seem work correctly. example @ moment using

ps -e -o command

which gives me...

line:  2729 ?        00:02:53 chrome line:  2824 ?        00:00:00 cat line:  2825 ?        00:00:00 cat line:  2945 ?        00:00:00 chrome line:  2946 ?        00:00:00 nacl_helper line:  2959 ?        00:00:00 chrome line:  2962 ?        00:00:00 gconfd-2 line:  3120 ?        00:07:39 chrome line:  3179 ?        00:00:00 chrome line:  3296 ?        00:00:44 chrome line:  3500 ?        00:00:00 bash line:  3751 ?        00:07:27 java line:  3832 ?        00:00:00 file-roller line:  4832 ?        00:00:23 chrome line:  4883 ?        00:00:03 gnome-terminal- line:  6085 ?        00:00:51 chrome line:  6380 ?        00:00:06 chrome line:  7865 ?        00:00:16 chrome line:  8961 ?        00:00:06 chrome line:  9404 ?        00:00:43 chrome line: 10344 ?        00:00:02 chrome line: 10761 ?        00:00:05 chrome line: 11158 ?        00:00:00 java line: 11193 ?        00:00:00 sh

this not me doesn't display process names, , not seem accurate. when run java applications terminal , re-run program, running applications don't change when should expect see process added.

from java using

/bin/sh -c ps -e -o command

is there way this? or way isolate jps executable can pack project , use in portable manor?

when running jps jdk, output

3751 main 14015 jps **11503** updater.jar

when run ps -ef machine terminal, output

root     10519     2  0 20:25 ?        00:00:00 [kworker/5:0] root     11156     2  0 20:40 ?        00:00:00 [kworker/7:1] root   **11503**  6170  0 20:49 pts/1    00:00:01 java -jar game/updater.jar /home root   13031  2959  0 21:15 ?        00:00:13 /opt/google/chrome/chrome --type root     13071     2  0 21:19 ?        00:00:00 [kworker/4:2]

when run ps -ef java application, following , process id 11503 seen...

process process = runtime.getruntime().exec(new string[] {"/bin/sh", "-c", "ps", "-ef" });  line:  7865 ?        00:00:17 chrome line:  8961 ?        00:00:06 chrome line:  9404 ?        00:00:43 chrome line: 10344 ?        00:00:03 chrome line: 13031 ?        00:00:09 chrome line: 13098 ?        00:00:15 chrome line: 13961 ?        00:00:00 java line: 13996 ?        00:00:00 sh line: 13997 ?        00:00:00 ps

the issue /bin/sh -c in command. removing gave me correct output although still think jps better solution (the jps can isolated final size ~100mb)

there two different things here:

  1. what/how run ps command. personal take here: ps -ef - lists all processes "full" format. see this more information.
  2. how invoke , read output java. that, see here example.
