Powershell

Question

我注意到如果执行此脚本时出现正确的时间，它就会在 Do-While 循环中正常运行。如果脚本启动时时间不正确，它将永远停留在 while 循环中，永远不会重新检查 IF 语句。

我确实有它们作为 else-ifs，但将其更改为故障排除。没用。

有谁知道为什么即使 do-while 设置为无限循环，嵌套的 IF 语句在时间正确后也不会执行？

我知道实际的 IF 条件确实有效，我已经测试过了。

脚本正在测试是否是 31 天、30 天、28 天、星期五和下午 5 点后一周中的任何一天的结束。

我想每 10 分钟检查一次这些条件，但您会看到我用了 5 秒进行测试

$WShell = New-Object -com "Wscript.Shell"
$Time=(Get-Date -Format HH:mm)
$Month=(Get-Date -Format MMMM)
$Day =(Get-Date -Format dd)
$Minute=(Get-Date -Format mm)
$DayName =(Get-Date -Format dddd)
$SleepTime = 10

DO{

if ($Month -eq "August" -or $Month -eq "January" -or $Month -eq "March" -or $Month -eq "May" -or $Month -eq "July" -or $Month -eq "October" -or $Month -eq "December" -and $Day -eq "31" -and $Time -gt "15:30" -and $Time -lt "15:49" )
{#for months with 31 days

"It's the end of a 31 day month, please save and submit your timesheets"
 Start-Process "Do something"
 Start-Sleep -Seconds $SleepTime
 
}
if ($Month -eq "April" -or $Month -eq "June" -or $Month -eq "September" -or $Month -eq "November" -and $Day -eq "30" -and $Time -gt "15:30" -and $Time -lt "15:49" )

"It's the end of the week, please submit and save your timesheet"
Start-Process "Do something"
Start-Sleep -Seconds $SleepTime

}
if($Time -gt "08:26"-and $Time -lt "17:14"){

"It's not the end of the week or month, no need to submit"
Start-Process "Do something"
Start-Sleep -Seconds $SleepTime

}

#"is it time to do timesheets? Not yet"
#"Checking again in 10 Minutes"

"testing while loop" 

Start-Sleep -Seconds 5

}while($true)

Answer 1

在开始 Do/While 循环之前，您只会获得一次 date/time，因此 date/time 变量将始终相同。

您需要将以下内容移动到您的 Do 块中，以便这些变量在每个循环中随当前时间更新。

$Time=(Get-Date -Format HH:mm)
$Month=(Get-Date -Format MMMM)
$Day =(Get-Date -Format dd)
$Minute=(Get-Date -Format mm)
$DayName =(Get-Date -Format dddd)
