How to kill process and his children?

[tomecki24]

Hello,

I've got a question.
I'm using Solaris 7.
I'm starting a script, which starts another one, which starts the last one. When I kill the first script the both two are still working.
How can I kill them all?

Thanks
Tomasz

How does the first script start the other 2? Does it use nohup?

Are these processes related to the first? (look at the output of ps -ef <process>). If they are and they're not being killed when the parent dies, are they being designated <defunct>? Can you post back with the output of your ps. Thanks.

Hello,

So, the first script is like this (mb_start.sh):
#!/bin/ksh
clear
/usr/storck/mb/bin/mb_bank > /usr/storck/mb/log/mb_bank_output.log &

The second one, mb_bank:
/usr/tibco/mb/bin/mbengine.sh -repourl tibcr://TestBAPI:service=7500:network=IP:daemon=tcp:IP:7500 -transformation TransName -engine TransEngine

And the third (mbengine.sh - already written) is:
... a lot of variables ...
/usr/j2se/bin/java -Xms8mb -Xmx64mb -Dae=TIBMBengine -Dcfg.editors=com.tibco.mb.ui.MessageBrokerEditor -classpath &quot;$LOCAL_MB_CLASSPATH&quot; com.tibco.mb.engine.EngineMode $*

Hello,

Here is the result of ps:

tibco 16605 1 0 11:49:19 pts/9 0:00 /bin/sh start_mb

tibco 16606 16605 0 11:49:19 pts/9 0:00 /bin/sh /usr/tibco/mb/bin/mbengine.sh -repourl tibcr://TestBAPI:service=7500:ne

tibco 16607 16606 0 11:49:19 pts/9 0:11 /usr/j2se/bin/../bin/sparc/native_threads/java -Xms8mb -Xmx64mb -Dae=TIBMBengin

When I will kill the first process, the other run normally.

Best regards
Tomasz

Guess: Could be that because your first script is put in the background with &, it doesn't send a kill to the spawned processes when it is killed. What happens if you don't put it in the background (if it's possible to test it like that)?

hello,

Yes, that's right, the first script is in background.
When I start it normally (in foreground I mean), Ctrl+C kills everything.
But the problem is I need them to be run in background, becuse they are java classes, and they &quot;lock&quot; terminal.

Best regards
Tomasz

Try putting &quot;.$$&quot; at the end of each command. This should start all the processes with the same PID. Like this:

/usr/storck/mb/bin/mb_bank /usr/storck/mb/log/mb_bank_output.log.$$ &
