Renaming a process

engee · 06-15-2009, 09:39 AM

Hi!

I've tried to search the forum for an answer to my question, but I've been unable to find a suitable one.

What I want to do is rename/change what is displayed as "cmd" when doing a ps -ef.

My goal is to have a more streamlined display of these and other processes running in the system, so that I can monitor them more easily.

Below is a sample of what I want to truncate into something more usable.

Code:

bin/dna -Djava.class.path=classes:../classes/diacommon.jar:classes/dna.jar -Djavax.net.ssl.keyStore=../config/mykey -Djavax.net.ssl.keyStorePassword=password -Djavax.net.ssl.trustStore=../config/mykey -Djava.security.policy=file:../config/rmipolicy.txt -Djava.security.auth.login.config=file:../config/diajaas.cfg -DCA_DIA_HOME=/opt/CA/SharedComponents/ccs -Djava.rmi.server.hostname=hostname.com com/ca/dia/dna/DNA

Is there some way to change what is displayed when starting the program, or perhaps afterwards?

Its quite technical, so you ought to have a bit of knowledge of

Code:

struct task_struct

in how the kernel implements processes

use "| cut -c n", where n is the num of characters you want in a line:
ps -ef | cut -c 80

This might help in some circumstances, but what I wish to achieve is to "permanently" rename the cmd, so that the processes will be reported as "java 1", "java 2" each time you do a regular ps -ef|grep java, these process will be monitored by another system, so the grep was just way to explain what I wanted to change.

This is more along what I have in mind, like you say it's quite technical so I'll have to do some thinking here, thank's for pointing me in the right direction.

This is probably not what you want either but you can make an alias to the ps command and use a bit of sed to get the name you want.
Anyway good luck and have fun with the setprocname program and please post here anything that you find and that might be useful to other people as well.
