this is a simple script . can it help find your way ?
Code:
os=ofs #old size
logFile=logFile

# test log file exists !
test -r $logFile || { echo "can't open $logFile"; 1>&2; exit 1; }

# get current log file size !
cfs=`ls -l $logFile | awk '{print $5}'`

# test to see file that keeps old size exists !
test -r $os || { echo 'not changed' 1>&2; echo $cfs>$os; exit 1; }

# old file size is empty !
if test `ls -l $os | awk '{print $5}'` -eq 0
then
        echo 'not changed' 1>&2;
        exit 1;
fi

oldsize=`sed -n '1,1p' $os`

if test $oldsize -eq $cfs
then
        echo 'not changed' 1>&2
else
        echo 'changed' 1>&2
fi

echo $cfs >$os

certainly above code with its structure can be write better and more efficient . i wrote it very quickly with my limited skill .
