Question

I am a newbie to linux. I am trying to find a command that displays
pid and java class.

I tried:

ps -C java -o pid 

but it only showed me pid, not java classes.

So I used a different command:

ps -ef | grep java"  

It showed me a full library of JAR files and associated java classes. However, I don’t need all of that information, I need only to display pid and java class.

The problem that I am facing is that sometimes the java processes take like 100M of memory and I can only know the pid with the command java on it by using linux command:

top

But it couldn’t find which java program is the one responsible for this. It will help me to debug that java file for memory leak.

Answer 1

ps aux | grep java

try this command and you can list of java process.
[or]

JPS will be helpful

JPS,JSTAT,JMAP,JSTACK,JHAT

you can run jps command it will show the pid value and based on these pid value others command will be executed.
