problem from process running in background

N Gopal — Thu, 20 Dec 2007 09:19:39 GMT

Hi,

Today i executed one scripts(.scr)which will generate reports(.csv file).

i run in this way

abc.scr &
it means i will run in backgound.
This script runs while loop and once records are over it teminates. It generates one CSV file as output.

I observed that this script is not getting terminated and cntinuously generatin records.
Files size is incerasing like anything. Actually it should process only 100 items.
Is any way to identify and kill this process?

Thanks

Hi

if you start your script in backgroud
you get some job-id

$ abc.scr &
[1]

$ now you can
$ kill %1

or
$ ps -ef | grep abc.scr

$ kill $the-pid-you-see

Or you can save the pid into a pidfile for later reference:

$ abc.scr &
$ echo $! >/tmp/abc.scr.pid
$ ps -fp $(/tmp/abc.scr.pid)
$ do-something-else
$
$ kill $(cat /tmp/abc.scr.pid)

But better you debug why your loop does not terminate. What kind of loop is there in your script?

Hi

see your background jobs with:

$ jobs
[1] running abc.scr &
[2] running efg.scr &

$ kill %1

You can also use "jobs -l" to get the PIDs.

You can also get a nice hierarchal listing of all of your processes with:
$ UNIX95= ps -Hfu $LOGNAME
