Second proccess question

[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.

Hi Mike,
Scripts in filesystems calls some programs. So i should avoid working them more than one proccess. But i shouldn`t kill first created 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

will kill second one which has started after first one
your ps command | awk '!/STARTPROC/{next}{if($NF in a)system("kill -9 "$2);a[$NF]}'

Hope This Helps, PH.
