Ok I found the mistakes
Im new to shell scripting/programming, anyhow learning from my mistakes

file1=/cygdrive/c/LogA.log
file2=/cygdrive/c/rLogB.log

Precount=`sed q $file1`
Postcount=`sed q $file2`
echo $Precount
echo $Postcount
if [ $Precount = $Postcount ]; then
echo "No Files Missing"
else
echo " Missing Files"
sdiff $file1 $file2 |grep '<'>>/cygdrive/c/Logc.log
fi

Correct me if anything wrong in above script
Thanks
