hi jim,
Thank you very much,
I got the solution and the problem is when we are trying taking variable "w" it is giving some errors i think "w" is internal system parameter .
I tried it with taking "t" as variable it got executed.

Thank you once again for helping me out JIM.

Lastly i have one dought "ps -ef|grep $processname | grep-v 'grep' | wc - l"
why did you grep -v 'grep' i havent used like this any time.

Hi Srini,

grep -v 'grep' would tend to filter the process output, not to include grep process.. Remember that it may be included as a process, and would confusions. So to be safe, that was added...

You can replace ps, grep and wc by pgrep

#!/bin/sh
if [ $(pgrep -c processname) -lt 3 ] ; then 
       echo "$processname Problem"
else 
       echo " Running Fine"
fi
