do nothing if condition is not met but not exit

Hello all, I created the below script....and it seemed to be working fine. My problem is i want the script to ignore rest of the things if my condition is not met but do not exit....

Code:

#!/bin/ksh
###########################
###########################

# Set name of the listener, this need to be upper or lower case
#LSNR=$1

echo "`basename $0` Start `date`."
for LSNR in $*
do

RM="rm -f"

echo "Listener name: $LSNR"

export user_id=`whoami`
export ORACLE_HOME=`ps -ef|grep tnslsnr|grep -v grep|grep -v sed|grep $user_id|grep $LSNR|awk '{print $8}'|uniq|sed "s#/bin/tnslsnr##g"`
export PATH=$ORACLE_HOME/bin:$PATH;

#check who owns the listiner
lsnr_ownr=`ps -ef|grep tnslsnr|grep -v grep|grep $LSNR|awk '{print $1}'|uniq`

if test $lsnr_ownr = $user_id; then
echo "Listener $LSNR is being ran as $lsnr_ownr owner"
else
echo "Listener $LSNR is owned by a different user -- aborting script"
echo "Run script using $lsnr_ownr user"
exit
fi

more cmd
more cmd
more cmd....
exit

so for above if $lsnr_ownr = $user_id; then it echo out something.... but if its NOT then it echo out something and EXIT.....

i do not want it to exit...just do nothing for rest of the script(more cmd, more cmd)....so how can i have it do nothing for rest of the script and exit out at very end after the more cmd ???

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
