searching for jobs already running

[ianholmes]

Hi

I have a script which runs a program “JobName”,
with a run-time parameter (A or B).
I take in the parameter, and add “.job” to it before executing it.
I need to enhance my script to check for the job already running with this parameter, and not to attempt to run it if it is already running.

When it runs, if I run :- ps -eaf | grep JobName

I see whoever whenever …path/JobName A.job
& whoever whenever .path/JobName B.job

if they are both running, which is fine.

How do I also identify the “x.job” ?

Help !

in your script......$1 is your passed parameter
if grep ${1}.job > /dev/null
then
echo "Job running"
else
echo "Job not running"
do whatever to run the job.....
fi

Thanks Dickie Bird
I actually take in 3 arguments, say 1, 2 & 3, and construct the passed parameter as 1_2_3.job.

When I run
if ps -eaf | grep ${1}_{2}_{3}.job > /dev/null,
it doesn't work
or even ps -eaf | grep ${${1}_${2}_${3}}.job > /dev/null
or even with " " around the underscores.

What should the syntax be ?
Thanks again.

Hmmmmmm.........
I tried :
#!/bin/ksh
if ps -ef|grep $1-$2|grep -v grep
then
echo found
else
echo not found
fi
having 2 params passed in - and it worked fine !
(further piped grep -v to avoid finding the grep command too ! )
Try the grep(with values) at the command line.

HTH
