Awk 将该栏汇总并放在该栏旁边,awk,Awk,我有一个像这样的文件 2291, 382718.00 2291, 19338.00 2291, 9073.00 2292, 4707.00 2293, 495847.00 2293, 157310.00 2293, 63582.00 2293, 100059.00 2293, 2843.00 2293, 58597.00 2293, 14836.00 2293, 24204.00 我想对第二列求和，并将结果放在最后一条记录旁

我有一个像这样的文件

我想对第二列求和，并将结果放在最后一条记录旁边每当第一列值更改时

id,             amount,              total
2291,   382718.00 ,   
2291,    19338.00 ,   
2291,     9073.00 ,   411129.00

2293,    14836.00 ,   
2293,    24204.00 ,   917278.00

我的程序正在添加所有第二列值并给出结果最后。如何根据第一列的值分解总计

   awk -F, '{ 
      a[NR] = $0
      sum  += $2
    }
    END {
      for (x = 1; x <= NR-1; x++) {
        printf"%s\n", a[x]
      }
      printf"%s %s\n", a[NR],sum
    }'

awk-F'{
a[NR]＝$0
总和+=$2
}
结束{
对于（x=1；x第一种解决方案：请尝试以下内容
awk '
BEGIN{
  FS=", +"
  OFS=", "
}
prev!="" && prev!=$1{
  print prev_line,sum
  sum=""
}
prev==$1{
  print prev_line
}

  sum+=$2
  prev=$1
  prev_line=$0

进行漂亮的打印：

谢谢。但这并不是打印所有行。只要在第一列的值发生变化时汇总并打印最后一条记录。@var，好的，请检查一下，让我知道这是否对您有帮助？@var，不客气，您真的应该一次看到这个链接。一旦得到答案，您能做什么cheers@RavinderSingh13只是rt给他们带图片的版本：谢谢。但这并不是打印所有行。只要在第一列的值发生变化时汇总并打印最后一条记录。@var，好的，修复了，请检查一下，让我知道这是否对您有帮助？@var，欢迎您，您真的应该一次看到这个链接。一旦得到ans，您可以做什么我们就这样cheers@RavinderSingh13只要开始给他们带图片的版本：
