過去x日間のデータを蓄積する方法

尋ねる：問題の主張のために、今日は26/03/15だとします。過去 5 日間のデータをどのように「累積」できますか？

しかし、この日付は単なる例です。。理想的には、最終データを蓄積したいと思います。X数日、累積されたら、蓄積された情報をメールでお送りします。私はこのプロセスを一日にしますジ数週間、crontabを介して助けを得る。

コードは次のとおりです。

awk_variables=`echo "$line" | awk -F, '( $13 == "*OUT*" )||( $13 == "*IN*" ){print $1,$5,$10,$12,$13}' my_file.csv > /directory/some_directory/non_sorted_filtered.csv`

cat /directory/some_directory/non_sorted_filtered.csv | while read line
do

        awk_variables="$line"
        awk_variables_array=($awk_variables)

        awk_time=${awk_variables_array[0]}
        awk_container_ID=${awk_variables_array[1]}
        awk_scan_count=${awk_variables_array[2]}
        awk_part_number=${awk_variables_array[3]}
        awk_direction==${awk_variables_array[4]}

        awk_part_number_edited="${awk_part_number:3}"
        awk_direction_edited="${awk_direction:1}"

        awk_date=@''$awk_time
        date=`date -d $awk_date +"%d/%m/%Y"`


        echo -e "Date:$date   Scan No:$awk_scan_count   Part No:$awk_part_number_edited  Direction:$awk_direction_edited"


done

出力は次のとおりです。

気づく:1日に検査する回数はさまざまです。時には100（たとえば）、時々ゼロです。
