Kシェル上でフラットファイルの条件付き集計をしたい。
いつもお世話になっています。Kornシェルで、以下のようなcsv形式のファイルを次の様に集計したいです。
<列A,C,D,E,F,G が全て一致する行毎に列Fの値を集計>
(入力)
列A------列B------列C----列D---列E--列F-----列G------列F
"10001","0090300", 11110," "," "," "," ",1013134
"10001","0090300", 11130,"0009","888","01","5050455",28428260
"10001","0090300", 11130,"0001","001","01","1111111",258925
"10001","0090300", 11165,"9900","999","09","9999903",0
"10001","0090300", 11110," "," "," "," ",592092
"10001","0090400", 11130,"0009","129","01","1018224",12489867
"10001","0090300", 11130,"0001","001","01","1111111",200000
"10001","0090400", 11165,"9900","999","09","9999904",834592
"10001","0090700", 11110," "," "," "," ",300000
(期待する出力)
"10001","0090300", 11110," "," "," "," ",1905226 <--- 1行目, 5行目, 9行目が集計されている
"10001","0090300", 11130,"0009","888","01","5050455",28428260
"10001","0090300", 11130,"0001","001","01","1111111",458925 <--- 3行目と7行目が集計されている
"10001","0090300", 11165,"9900","999","09","9999903",0
"10001","0090400", 11165,"9900","999","09","9999904",834592
"10001","0090400", 11130,"0009","129","01","1018224",12489867
出力のソートの必要はありません。
これをシェル・スクリプトだけで実装するのは、無理でしょうか。良いアイディアをお願いします。
