Shell Programming and Scripting

I agree, that would not hinder the running process.

Its more like a warning and that could be very much ignored.

Hi Porter/matrixmadhan,

I dare not experiment with this command as it is very new to me and i hope that the system will not collapse because of this if not everybody will start to scream at me. So i will have to really make sure everything is ok before i try out.

Can the below command stop the process manually?

ps -aef
kill -9 pid ?

Try with a small dummy script such as

Code:

#!/bin/sh
while true
do
    sleep 1000
done

Have a couple of terminal sessions open, run it from one, monitor it from both using "ps" then close the terminal you used to launch it.

You need to gain confidence in what it will and won't do.

Hi Porter,

I tried your dummy script.
I tired to kill the process using kill -9 11417 but I can't kill the process.
Help me pls!!

nohup testing &

After executing ps -aef

Code:

user 11417     1  0 16:19:26 ?        0:00 sleep 1000

Are you sure of the process id of the nohup process that is kicked off ?

What is the return status after issuing kill command ?

check it with >> echo $?

How did you confirm that kill command is not working ?

I think you killed the shell running the script that's good.

but what you are seeing is the "sleep 1000" program is still running, it's parent has died hence it being reparented to the init process (pid=1)

Does "kill -9 11417" return an error?

Hi Porter,

I tried several time before the process can be killed. It will return a " Killed " if successful
The kill command did not return anything at my 1st try.
I tried out serveral time but somehow the process canot be killed during my 1st try.

Yeah indeed the PID and PPID changed to another number!!
But what is the reason for reparenting to the init process (pid=1) ??
