nope, not close yet - I recommended looking into "fuser"

let's call this script kas.sh

and let's invoke it as:
(./kas.sh &); sleep 2;./kas.sh
Code:
#!/bin/ksh
#

thisFILE="$(whence ${0})"
progName="${0##*/}"

     myPID="$$"

     FUSERout=$(fuser ${thisFILE} 2>/dev/null)
     typeset -i numProc=$(echo "${FUSERout}" | nawk '{print NF}')
     if [[ "${numProc}" -gt 1 ]]; then
        echo "${progName}: another instance(s) of [${thisFILE}] is currently sti
ll running [$(echo ${FUSERout} | sed -e 's/  */ /g')] - exiting THIS [${myPID}]run."
        exit 1
     fi

     sleep 5
     echo "finished->[${myPID}]"

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

NAME

       checksecurity - Run a collection of simple system checks

SYNOPSIS

       checksecurity

DESCRIPTION

       The checksecurity command runs a small collection of simple system checks which are designed to catch a few common security issues.  check-
       security is run by cron in a daily basis.

CONFIGURATION

       The checksecurity.conf file defines several configuration variables: MAILTO, CHECK_DISKFREE, CHECK_PASSWD and CHECK_SETUID LOGDIR.  Each is
       described below.

       The  checksecurity program works with a collection of plugins which are located in /usr/share/checksecurity and are configured individually
       by their own configuration file.

       CHECK_PASSWD If this is set to TRUE then the check-passwd script will be invoked.  This script is designed to report upon  system  accounts
       which  have  no passwords.  CHECK_DISKFREE If this is set to TRUE then the check-diskfree script will be invoked and will allow an alert to
       be sent if there is any mounted partition is running short on disk space.  CHECK_SETUID If this is set to TRUE then the check-setuid script
       will be invoked, this will compare the setuid binaries upon the system to those that existed previously and show the differences.

FILES

       /etc/checksecurity.conf
	      checksecurity configuration file
