bash中日志文件的输出不正确

我有一个输入文件，如下所示：

Date: 01-01-2007
thing1    3    7098    22394
thing2    2    6500    13000
thing3   20    300    6000
Overalltotal: 41394
-----------------------------------
Date: 04-01-2007
thing1    10    700    5000
thing2-Card    48    900    43200
Overalltotal: 46020

---

电流输出：

Error in calculations:
Things total for thing1 is wrong: it should be 7000 instead of 5000
Overalltotal is wrong: It should be 50200

预期产出：

Error in calculations:01-01-2007
    Things total for thing1 is wrong: it should be 21294 instead of 22394
    Overalltotal is wrong: It should be 40294
Error in calculations:04-01-2007
    Things total for thing1 is wrong: it should be 7000 instead of 5000
    Overalltotal is wrong: It should be 50200

for f in *.log; do  
  awk '
    /Date/ {
      date=$2;
    }

    NF > 2 {
      r = $2*$3;
      if(r != $4) {
        check_if_first_error();
        printf "\tThings total for %s is wrong: it should be %d instead of %d\n", $1, r, $4;
      }
      overall_total += r;
    }

    /total/ {
      if (overall_total != $2) {
        check_if_first_error();
        printf "\tOveralltotal is wrong: it should be %d instead of %d\n", overall_total, $2;
      }
    }

    function check_if_first_error() {
      if (!has_previous_error) {
        printf "Error in calculations: %s\n", date;
        has_previous_error = 1;
      }
    }
    ' "$f"
done &>error_log

迄今为止的代码：

#!/bin/bash

# To create new files based on each date and copy the contents till the dashed line.
awk -F' ' '{fn=$1".log";sub(/^.* /,"",fn);print>fn;close(fn)}' \
    FS='\n' OFS='\n' RS='---+\n' ORS='' $1 

for f in *.log; do  
    (awk 'NF && NR>1 && $0!~/total:/{
     r=$2*$3; v=(v!="")? v"+"r : r; 
     if(r!=$4){ things_er[$1]=r" instead of "$4 }
         err_t+=$4; t+=r; $4=r
     }
     $0~/total/ && err_t { 
     print $1,"("v")",$3,t; print "Error in calculations:" | "cat 1>&2"; 
         for(i in things_er) { print "Things total for "i" is wrong: it should be "things_er[i] | "cat 1>&2"; } 
         print "Overalltotal is wrong: It should be "t | "cat 1>&2"; next 
     }1' "$f") 2> error_log
 done

在我的错误日志文件中，我没有在计算中看到第一个日期的错误，我还需要在错误日志文件中打印日期。有谁能告诉我为什么2007年1月1日的计算错误不会出现？另外，如何按预期输出打印日期？

您的代码过于复杂和混乱。最好从头开始

for

循环中的以下AWK命令打印所需输出：

Error in calculations:01-01-2007
    Things total for thing1 is wrong: it should be 21294 instead of 22394
    Overalltotal is wrong: It should be 40294
Error in calculations:04-01-2007
    Things total for thing1 is wrong: it should be 7000 instead of 5000
    Overalltotal is wrong: It should be 50200

for f in *.log; do  
  awk '
    /Date/ {
      date=$2;
    }

    NF > 2 {
      r = $2*$3;
      if(r != $4) {
        check_if_first_error();
        printf "\tThings total for %s is wrong: it should be %d instead of %d\n", $1, r, $4;
      }
      overall_total += r;
    }

    /total/ {
      if (overall_total != $2) {
        check_if_first_error();
        printf "\tOveralltotal is wrong: it should be %d instead of %d\n", overall_total, $2;
      }
    }

    function check_if_first_error() {
      if (!has_previous_error) {
        printf "Error in calculations: %s\n", date;
        has_previous_error = 1;
      }

首先，您必须了解AWK是如何工作的：AWK程序是一系列

pattern{action}

语句。每一行（或者更准确地说，每一条记录，默认情况下是一行）按顺序与每个

模式

进行比较，如果它与模式匹配，则执行

{action}

。因此，在我的回答中有三种模式，第一种模式匹配“日期”行，第二种模式匹配所有“事物”行，第三种模式匹配“总计”行。函数的工作原理与其他任何编程语言中的工作原理一样。它们可以在代码中的任何地方定义，它们不是在定义它们的地方执行，而是在调用它们的地方执行（在我的答案中有两处）。我引入此函数的唯一原因是为了避免代码段（函数体中的代码）的重复。只需将语句

check\u if\u first\u error（）

替换为函数体中的代码，就可以在没有函数的情况下重写代码。
