AIX/Linux - How to get pid for a running shell script using ps command

Hi,

I wrote a shell script to find out the process that is running a same command. In the shell script I use

NPID=`ps uxc | grep -i -w "$CName" | awk '{print $2}' | wc -l`

#NPID will return the number of process that is running the command $CName

PID=`ps uxc | grep -i -w "$CName" | awk '{print $2}'

#PID will return the pid of the process that is running the command $CName

This all goes well. However, if the $CName is not an executable but it is a shell script
then the above line won't work. I guess it is because the shell script is not an executable.

Is there anywhere I can get the NPID and PID for shell script?

In fact, for my purpose. I will have multiple process each running the same shell script. So, I want to know how many process are running the same shell script. An I also want to get (using ps command)  their pid.  All these have to be done in a shell script.

Any idea how to do that.

Thanks!
