i copied this script from elsewhere, i am learning. i am glad you gave some input. thanks. to answer your questions to help:

1. Why does your script initialize BATPF twice?
it doesn't, typo, it will be removed. thanks for noticing that DON!

2. yes it does start a process - another script, a batch script actually that is suppose to run and accept requests to a client driven db - we won't get into that.

3. Why bother setting pid to an empty string just before exiting when the service is running?
I didn't, I do not know what I am doing. I'm trying though.

The sleep is there in the hopes that it will produce a new $pid, that is one thing that is puzzling me the most.

Like I said before, the script runs fine ( the one this is calling ) and needs to be online 24/7. This script is supposed to CHECK to see if ANY pid matches the grep in BATPF. it takes 10 seconds for a new pid to be reproduced. I am trying to wait/sleep/capture that new pid in the "if".

Is there a better way?

Don I will try to do the steps you suggested. Looks like it will work. But remember, I need this script to end. so running it in background process with & looks great, but will take 10 seconds for that new pid to come avail? If I start the backend script, it takes a few mins to produce a pid(the backend is a db starting with a client) and usually takes same amount of time for pid via ps and grep to show its not there - aka gracefully shutdown that connection. DB is heavy transaction based.

thanks, hope that helps. pls ask anything more. thanks guys...

SERVICE(8)                                                    System Manager's Manual                                                   SERVICE(8)

NAME

       service - run a System V init script

SYNOPSIS

       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION

       service  runs  a System V init script or systemd unit in as predictable an environment as possible, removing most environment variables and
       with the current working directory set to /.

       The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT, or the name of a systemd unit.  The  existence  of  a
       systemd unit of the same name as a script in /etc/init.d will cause the unit to take precedence over the init.d script.  The supported val-
       ues of COMMAND depend on the invoked script. service passes COMMAND  and OPTIONS to the init script unmodified. For systemd  units,  start,
       stop, status, and reload are passed through to their systemctl/initctl equivalents.

       All scripts should support at least the start and stop commands.  As a special case, if COMMAND is --full-restart, the script is run twice,
       first with the stop command, then with the start command.

       service --status-all runs all init scripts, in alphabetical order, with the status command. The status is [ + ] for running services, [ - ]
       for stopped services and [ ? ] for services without a status command.  This option only calls status for sysvinit jobs.

EXIT CODES

       service calls the init script and returns the status returned by it.

FILES

       /etc/init.d
              The directory containing System V init scripts.

       /{lib,run,etc}/systemd/system
              The directories containing systemd units.

ENVIRONMENT

       LANG,  LANGUAGE,  LC_CTYPE, LC_NUMERIC, LC_TIME, LC_COLLATE, LC_MONETARY, LC_MESSAGES, LC_PAPER, LC_NAME, LC_ADDRESS, LC_TELEPHONE, LC_MEA-
       SUREMENT, LC_IDENTIFICATION, LC_ALL, TERM, PATH
              The only environment variables passed to the init scripts.
