Question

我有两个文本文件如下。其中包括每个项目的数量，价格，总数和所有项目总数。

file1.txt

Date: 05-10-2016
Item1 5 1000 6000
Item2 7 1500 10500
Item3 4 2000 8000
Total: 24500

file2.txt

Date: 07-12-2016
Item1 7 750 5250
Item2 3 900 2700
Item3 8 1000 9000
Total: 16950

我试图通过添加文件中存在的单个项目价格来再次阅读每个文件和总计。如果总数不匹配，则应在error.txt文件中写一条错误消息，明确说明数据存在问题的日期。

error.txt

Date: 05-10-2016
Item1 5 1000 6000 : Item total calculation is wrong.
Total: 24500 : All items total calculation is wrong.

Date: 07-12-2016
Item3 8 1000 9000 : Item total calculation is wrong.
Total: 16950 : All items total calculation is wrong.

Answer 1

awk '/Date/{d=$0;t=0;p=0;next;}
     /Total/{if(t!=int($2)){if(p==0){print d; p=1;}; print $0,":","All items total calculation is wrong."};next;} 
     {k=int($2)*int($3);t+=k;if(k!=int($4)){if(p==0){print d; p=1;}; print $0,":","Item total calculation is wrong."}}' file1 file2 >error.txt

输出：

cat error.txt

Date: 05-10-2016
Item1 5 1000 6000 : Item total calculation is wrong.
Total: 24500 : All items total calculation is wrong.
Date: 07-12-2016
Item3 8 1000 9000 : Item total calculation is wrong.
Total: 16950 : All items total calculation is wrong.

bash：从输入文件中读取并执行计算并将错误写入日志文件
