if [ "$seconds" = "" ] && [ "$minutes" = "" ] && [ "$hours" = "" ]; then
        grep "$dates/$month/$years" access.log | grep 'MOBILENO_QUERY'| wc -l;
elif [ "$seconds" = "" ] && [ "$minutes" = "" ]; then
        grep "$dates/$month/$years:$hours" access.log | grep 'MOBILENO_QUERY'| wc -l;
elif [ "$seconds" = "" ]; then
        grep "$dates/$month/$years:$hours:$minutes" access.log | grep 'MOBILENO_QUERY'| wc -l;
else
        grep "$dates/$month/$years:$hours:$minutes:$seconds" access.log | grep 'MOBILENO_QUERY'| wc -l;
