如何先运行一个exe，然后等待5秒钟，然后在批处理文件中运行另一个exe

Question

calcAverageRating(ratings) {

  let totalWeight = 0;
  let totalReviews = 0;

  ratings.forEach((rating) => {

    const weightMultipliedByNumber = rating.weight * rating.count;
    totalWeight += weightMultipliedByNumber;
    totalReviews += rating.count;
  });

  const averageRating = totalWeight / totalReviews;

  return averageRating.toFixed(2);
}


const ratings = [
  {
    weight: 5,
    count: 252
  },
  {
    weight: 4,
    count: 124
  },
  {
    weight: 3,
    count: 40
  },
  {
    weight: 2,
    count: 29
  },
  {
    weight: 1,
    count: 33
  }
];

console.log(calcAverageRating(ratings));

我正在使用Windows 10 64位。我想做的是先运行a.exe。然后等待5秒钟并同时运行b和c。但它们都同时开始运行

Answer 1

SLEEP无法识别为内部或外部命令，可操作程序或批处理文件。尝试使用TIMEOUT /T 5 >NUL。

Answer 2

我推荐Powershell。

& "C:\Program Files (x86)\Notepad++\notepad++.exe"
Start-Sleep -Seconds 5
& "C:\Program Files\JetBrains\PyCharm Community Edition 2018.3.5\bin\pycharm.exe"

仅作为示例

希望有帮助！ BR
