second proccess 1

[unixisgood]

Hi all,
I need a script that will look for some running proccess.Proccess names are have same content as `STARTPROC` but those works for all filesystem ,it will also look that any duplicates of them. STARPROC has to be work only once for every single filesystem.

regarding below proccess list . The script will check that is there any duplicate proccess. For example there are two /a5/script/STARTPROC, it will kill second one which has started after first one. I assume script can catch this from starting time of proccess.


/a1/script/STARTPROC
/a2/script/STARTPROC
/a3/script/STARTPROC
/a4/script/STARTPROC
/a5/script/STARTPROC
/a5/script/STARTPROC
/a6/script/STARTPROC
/a7/script/STARTPROC
/a8/script/STARTPROC
/a9/script/STARTPROC

If is this possible to write a script i will put it into crontab file to run it every 10 minutes.

Thanks for any help.

A starting point (typed, untested):
ps -fe | awk '!/STARTPROC/{next}{if($NF in a)system "kill -9 "$2;a[$NF]}'

Hope This Helps, PH.

Hi PHV,
Thanks for answer but it doesn`t work.
Maybe i can check for proccess id. I mean something like if proccess id is greater than first one kill the latest same proccess.

Does anyone know how to do this. If no is there also possiblity to have only a warning message to session of root user.

For example from ps output
user8 21049 1 0 00:00:01 ? 0:14 /a8/script/STARTPROC
user7 21049 1 0 00:00:01 ? 0:14 /a7/script/STARTPROC
user8 21049 1 0 00:00:01 ? 0:14 /a8/script/STARTPROC
user9 21049 1 0 00:00:01 ? 0:14 /a9/script/STARTPROC

Warning! "/a8/script/STARTPROC" has duplicate process. Kill it immediately.

Thanks for any help

Sorry for the typo:
ps -fe | awk '!/STARTPROC/{next}{if($NF in a)system[!]([/!]"kill -9 "$2[!])[/!];a[$NF]}'

Hi PHV
Many thanks . It works but not exactly like what i want. It should include also filesystem name to not kill other processes works in different filesystems.

I have tried with puting file system name but got error. So i guess i need to put a syntax to able to add it. Can you help about this please?

ps -fe | awk '!/a8/STARTPROC/{next}{if($NF in a)system("kill -9 "$2);a[$NF]}'
syntax error The source line is 1.
The error context is
>>> !/a8/STARTPROC/{ <<<
awk: Quitting
The source line is 1.

$NF include the filesystem, so only duplicates in a filesystem are killed.

Hope This Helps, PH.
