Bom dia! Eu tenho um arquivo .CSV com 9 colunas. Preciso analisar seu conteúdo em um novo arquivo, realizar alguns pequenos cálculos e criar uma nova linha no processo. Acho que isso é melhor ilustrado mostrando o .CSV existente e a saída desejada:

Como você pode ver na saída desejada, preciso de algumas coisas novas:

  • Duplicar 1ª, 3ª e 5ª colunas da linha anterior se a próxima linha forNULL
  • Se a 5ª coluna na linha anterior for NULL, imprima N/Aem vez disso
  • Altere todas as entradas na 2ª coluna para Expense(de General Journal)
  • A 8ª coluna (Débito) é o valor existente menos 13%
  • Insira uma nova linha e calcule o imposto HST (13%)

O que eu fiz até agora? Pesquisei em todo o StackExchange e encontrei o seguinte ( deste post :)

    awk '{
       split($0,D,/[^[:space:]]*/);
       s = "";
       for(i=1;i<=NF;i++){ 
            if($i~/NoData/){ $i =  last[i]; } 
            last[i]=$i ; 
            s = s  sprintf("%s%s",D[i],$i) 
       }  
       print s
 }' file
awk csv
