周中循环+营业时间

Question

我正在写一个脚本，它只在上午8点到下午5点运行。问题是，当它从8-5或M while()循环中掉下来后，它只是.不知道如何重新进入循环。这使我想，我可能是从错误的角度接近我的脚本。也许有更好的方法。

“做点什么”部分是比较同一文件之间5分钟间隔的文件大小。这是为了检查文件是否正在增长/缩小。

# Declare current date/time
$Weekday = [int](Get-Date).DayOfWeek
$hour = [int](Get-Date -Format HH)

while (1 -eq 1) {   # always true
    $Weekday = [int](Get-Date).DayOfWeek
    $hour = [int](Get-Date -Format HH)
    while ($Weekday -ge 1 -and $Weekday -le 5) {  # weekday
        $Weekday = [int](get-date).DayOfWeek    # loop check for current day
        while ($hour -ge 8 -and $hour -le 16) { # 8AM-5PM
            $hour = [int](get-date -format HH)  # loop check for current hour
            # Do Something
        }
        else {
            # Sleep until next business hour
            $date = Get-Date
            $date = $date.AddDays(1)
            $mmddyyy = $date.ToString("MM/dd/yyy")
            $nextDy = New-TimeSpan -End "$mmddyyy 08:00"
            Write-Host "Start sleep timer until next 8AM"
            Start-Sleep -Seconds $nextDy.TotalSeconds
        }
    }
    else {
        # Sleep until next business day
        $date = Get-Date
        while ($Date.DayOfWeek -ne "Monday") {$date = $date.AddDays(1)}
        $mmddyyy = $date.ToString("MM/dd/yyy")
        $nextBu = New-TimeSpan -End "$mmddyyy 08:00"
        Write-Host "Start sleep timer until next Monday 8AM"
        Start-Sleep -Seconds $nextBu.TotalSeconds
    }
}

1. 尝试使用计划的任务或服务。
2. 如果您想使用PowerShell脚本，请尝试使用以下命令： 时间($true) {#工作日$Weekday = 整型.DayOfWeek #循环检查当前日$hour = 整型如果($Weekday -le 5 -and $Weekday -ge 1) { while ($hour -ge 8 -and $hour -le 16) {#上午8时-下午5pm $hour =$hour#循环检查当前时间#做某事}} $date = Get-Date $date = $date.AddDays(1) $mmddyyy = $date.ToString("MM/dd/yyy") $nextDy = New-TimeSpan -End "$mmddyyy 08:00“写-主机”启动睡眠定时器，直到下一个上午8点“开始-睡眠-Seconds $nextDy.TotalSeconds }

我觉得你完全搞错了。

最好使用像TestFileSizeUtil这样的简单库函数来实现监视文件大小，或者像这里那样使用WMI。

$query = "Select * from __InstanceModificationEvent WITHIN 5 WHERE TargetInstance ISA 'CIM_DataFile' AND TargetInstance.Name='C:\\Logs\\test.log'"

Register-WmiEvent -Query $query -Action {
    Write-Host "Current file size is: " $Event.SourceEventArgs.NewEvent.TargetInstance.FileSize
    $prevSize = $Event.SourceEventArgs.NewEvent.PreviousInstance.FileSize
    $curSize = $Event.SourceEventArgs.NewEvent.TargetInstance.FileSize
    if ($curSize -gt $prevSize) {
        $bytes = $curSize - $prevSize
        Write-Host "File grew by: $bytes bytes"
    } else {
        $bytes = $prevSize - $curSize
        Write-Host "File reduced by: $bytes bytes"
    }
}

那么，如果您的脚本一整天都在运行，那就不重要了。
