Question

我有这么长的路线：

kvm1.example.corp,18:18:48,x86_64,16,11,11,0,0,0,0,0,11,0,4.6,99056376,4980736,4980736,5450000000,1,s-75-VM,460000000.,0.385304090422,262144,0,0,3,743,0,2,v-30-VM,450000000.,0.376927914543,1048576,1,0,6,7676,4765,3,r-80-VM,430000000.,0.360175562786,131072,0,0,0,208,0,5,i-2-81-VM,10000000.,0.00837617587873,1048576,1,0,0,0,0,6,r-83-VM,430000000.,0.360175562786,131072,0,0,0,156,0,7,i-3-82-VM,710000000.,0.59470848739,524288,0,0,0,0,0,8,r-85-VM,410000000.,0.343423211028,131072,0,0,0,208,0,11,i-3-84-VM,710000000.,0.59470848739,524288,0,0,0,0,0,12,i-2-79-VM,690000000.,0.577956135633,524288,0,0,2,0,0,13,r-87-VM,420000000.,0.351799386907,131072,0,0,0,156,0,14,i-3-88-VM,730000000.,0.611460839147,524288,0,0,2,0,0

我正试图像这样输出

我不确定在删除标题后第9个逗号后添加新行应该采用哪种策略？

Answer 1

awk -F, '{for (col = 19; col < NF; col += 10) {
           for (i = 0; i < 10; i++) { printf("%s,", $(col+i)); }
           printf "\n"; }
         }'

Answer 2

使用sed更简单：

$ sed -r 's/([^,]+,){18}//;s/(([^,]+,){10})/\1\n/g' file

Answer 3

在bash中：

(
  IFS="," read -a fields <<< "$longline"
  set -- "${fields[@]:18}"
  IFS=","
  while (( $# > 0 )); do
    echo "${*:1:10}"
    shift 10
  done
)

(...)创建一个子shell，这样我们就不必担心保留IFS的旧值和shell参数（$@和$*）。

第一行使用'，'作为字段分隔符拆分长行，并将字段存储在数组中。

第二行跳过前18个字段（所有标题元素）并将其余字段存储在shell参数中，可以使用$1，$2等单独访问，也可以共同{{1 }或$@。

第三行为while循环的其余部分创建字段分隔符'，'，特别是$*命令中的参数扩展。

echo获取前10个shell参数，并使用"${*:1:10}"的值连接它们。

shift 10丢弃前10个参数（我们刚刚打印）。

IFS是shell参数的数量，在每次$#操作后减少10;只要还有要处理的参数，循环就会继续。

in perl：

perl -F, -lane 'for($min=18;$min<scalar(@F);$min+=10){print join ",",@F[$min..$min+10]}'

测试如下：
