Javascript 如何将vmstat和free-m转换为object？

我想将exec执行的vmstat-s命令的输出转换为对象，以及free-m命令out put

我从exec免费获得此信息-m:

              total        used        free      shared  buff/cache   available
Mem:           7855        2054        1082         257        4718        5243
Swap:          2047           0        2047

对于vmstat-s，我得到了这个输出

      8044160 K total memory
      2081200 K used memory
      3491012 K active memory
      2508932 K inactive memory
      1131132 K free memory
       579204 K buffer memory
      4252624 K swap cache
      2097148 K total swap
            0 K used swap
      2097148 K free swap
       328672 non-nice user cpu ticks
         3273 nice user cpu ticks
        85460 system cpu ticks
      4215038 idle cpu ticks
        13261 IO-wait cpu ticks
            0 IRQ cpu ticks
          450 softirq cpu ticks
            0 stolen cpu ticks
      2095462 pages paged in
      3761868 pages paged out
            0 pages swapped in
            0 pages swapped out
     10301935 interrupts
     36499667 CPU context switches
   1551158702 boot time
        17506 forks

那么，我如何将这个输出转换成像这样的对象呢

objFreeM = {
  mem: {total: 7855, used: 2054, ...etc},
  swap: {total: 2047, used: 0, free: 2047}
}

objVmstat = {
  totalmemory: 8044160,
  usedmemory: 2081200,
  ....etc
}

这是vmstat的结果

让我们初始化字符串：

var myString = "      8044160 K total memory\n      2517232 K used memory\n      4064068 K active memory\n      2733260 K inactive memory\n       304940 K free memory\n       650300 K buffer memory\n      4571688 K swap cache\n      2097148 K total swap\n            0 K used swap\n      2097148 K free swap\n       454507 non-nice user cpu ticks\n         3803 nice user cpu ticks\n       117177 system cpu ticks\n      7955496 idle cpu ticks\n        15791 IO-wait cpu ticks\n            0 IRQ cpu ticks\n          528 softirq cpu ticks\n            0 stolen cpu ticks\n      2244129 pages paged in\n      4442696 pages paged out\n            0 pages swapped in\n            0 pages swapped out\n     14232293 interrupts\n     50365325 CPU context switches\n   1551158702 boot time\n        22313 forks\n";

现在让我们将其拆分：

var myArray = myString.split("\n");

然后修剪项目：

for (var index in myArray) myArray[index] = myArray[index].trim();

为camel case键定义辅助函数：

function camelize(str) {
  return str.replace(/(?:^\w|[A-Z]|\b\w)/g, function(letter, index) {
    return index == 0 ? letter.toLowerCase() : letter.toUpperCase();
  }).replace(/\s+/g, '');
}

最后分析结果：

var results = {};
for (var item of myArray) {
    var temp = item.split(" ");
    var value = temp[0];
    var key = "";
    var start = 1;
    if (temp[1] === "K") {
        value += " K";
        start = 2;
    } else {
        key = "";
    }
    for (var index = start; index < temp.length; index++) key += " " + temp[index];
    key = key.trim();
    if (key || value) results[camelize(key)] = value; 
}

var结果={}；
for（myArray的变量项）{
var temp=项目拆分（“”）；
var值=温度[0]；
var key=“”；
var start=1；
如果（温度[1]=“K”）{
值+=“K”；
开始=2；
}否则{
key=“”；
}
对于（var index=start；index
