某一列的特殊处理

l1905

问题具体描述为

怎么我才能把以上文本转化为{“cs":128,"us":1,"sy":1,"id":1}这样的格式？
没想到用awk sed怎么实现。。。求各位指点

各位给个思路啊、、、先感谢了

看了下，貌似是获取vmstat的相关数据并转换格式，那直接执行以下代码即可：

1. vmstat | awk 'NR>1{if(NR%2==0){for(i=12;i<=15;i++)a[i]=$i;next}{for(i=12;i<=15;i++){l="\""a[i]"\"" ":" $i;s=s?s","l:l}print "{"s"}"}}'

How about this

$ vmstat | awk -vS=12 -vE=15 'NR==2{for(n=S;n<=E;n++)a[n]="\""$n"\":"}NR==3{printf "{"a[S]$S;for(n=S+1;n<=E;n++)printf(","a[n]$n);print "}"}'
{"cs":499,"us":2,"sy":13,"id":82}

LikeLx

vmstat |awk '$0!~/[a-z]/{print "{""cs:"$(NF-5) ,"us:"$(NF-4),"sy:"$(NF-3),"id:"$(NF-2)"}"}'
而且可以这样输出vmstat 1 |awk '$0!~/[a-z]/{print "{""cs:"$(NF-5) ,"us:"$(NF-4),"sy:"$(NF-3),"id:"$(NF-2)"}"}' 比较直观
