Bash 在逗号数后添加新行,bash,scripting,sed,awk,Bash,Scripting,Sed,Awk,我排了这么长的队： 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.,0.3601

我不确定在删除标题后，在第9个逗号后添加新行时应该采取哪种策略？

awk-F'{for（col=19；colawk -F, '{for (col = 19; col < NF; col += 10) {
           for (i = 0; i < 10; i++) { printf("%s,", $(col+i)); }
           printf "\n"; }
         }'
对于（i=0；i<10；i++）{printf（“%s，”，$（col+i））；} printf“\n”} }' 
使用
sed更简单
：


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

在bash中：


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



(
IFS=“，”在perl中读取-a字段：


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



perl-F，-lane'（$min=18；$min）谢谢你，我正在努力跟上awk，干得好！非常感谢！
