How to check file have a "SYSTEM" word or not

If SYSTEM does not eixsint in ${DBLOG}, LINES return blank line
LINES=`pr -n ${DBLOG} |grep 'SYSTEM' |tail -1`

If below command good or not ? Any improvement ?
if [ "$LINEONLY" -lt " " ] ; then

[ $LINEONLY > 1 ]

Main program

#!/bin/ksh
#
DBLOG=/database/ph.lg

# Tmp file
TMPFILE01=/home/ericl6/log/checklg.tmp

#

MAILTO_ME ()
{
echo MAILTO_ME
mailx -s "DBLOG ${DBLOG} have New SYSTEM Error" $ME <
cnt -l = $cnt_l
cnt -mmax = $cnt_mmax

`pr -n ${DBLOG} |grep 'SYSTEM'`

*** end of message ***
!
}

grep 'WARNING' ${DBLOG} |grep -v 'WARNING: -l exceed' |grep -v
'WARNING: -mmax exceeded'
cnt_l=`grep 'WARNING: -l exceed' ${DBLOG} |wc -l`
cnt_mmax=`grep 'WARNING: -mmax exceeded' ${DBLOG} |wc -l`

LINEONLY=NULL
LINES=`pr -n ${DBLOG} |grep 'SYSTEM' |tail -1`
LINEONLY=`echo $LINES| awk '{print $1}'`
#~~echo LINEONLY=$LINEONLY
rtn01=1
if [ -f $TMPFILE01 ] ; then
grep "$LONEONLY" $TMPFILE01 > /dev/null
rtn01=$?
else
if [ "$LINEONLY" -lt " " ] ; then
rtn01=1
fi
fi
if [ $rtn01 = 1 ] && [ $LINEONLY > 1 ] ; then
# New SYSTEM ERROR FOUND, Update line number in temp file
echo $LINEONLY > $TMPFILE01
MAILTO_ME
fi

I would do:

if grep -q SYSTEM "$DBLOG"
then ...
fi
