Powershell 重啟控制台問題

Question

我有一個登錄腳本，如果 PC 的運行時間超過允許的時間，它會重新啟動 PC。

我有一個 PowerShell 腳本，它在登錄期間運行並每周執行一次，以檢查機器的正常運行時間並在超過 48 小時時重新啟動。 該腳本允許用戶請求擴展，這樣他們就不會立即被踢出機器。 我有 1、3、8 小時的延期。 只有1、3小時的延期工作。 看起來如果你輸入一個大於 3 的值，它不接受它。 有沒有辦法讓這個“擴展”工作超過 3 小時？

我想允許延長 8 小時，但不允許超過 3 小時。

Answer 1

這是 shutdown.exe可執行文件的限制。 根據此處找到的文檔：

https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/shutdown

 
 
 
  
  /t <XXX> Sets the time-out period or delay to XXX seconds before a restart or shutdown. This causes a warning to display on the local console. You can specify 0-600 seconds. If you do not use /t, the time-out period is 30 seconds by default.
 
 

如果你想超越它，你必須在執行 shutdown.exe之前在 PowerShell 中創建一個暫停。 這可以通過在 8 小時選項中添加 start-sleep 、睡眠 3 小時，然后指定最大 600 秒計時器來完成。

編輯：看起來那個文檔已經過時了，關機現在可以接受長達 10 年的任何內容（以秒為單位格式化）。 看，shutdown 命令只需要幾秒鍾。 你應該能夠用秒 x 分鍾 x 小時來計算它，而不是你正在嘗試的所有花哨的數學。 一分鍾 60 秒，一小時 60 分鍾，所以唯一改變的是延遲的小時數。 嘗試這個：

 $Global:hash.ScheduleBtn.Add_Click( { $startTime = switch ($Global:hash.ScheduleValue.SelectedItem.Name) { "one" { 1*60*60 } "three" { 3*60*60 } "eight" { 8*60*60} } $Global:hash.Timer.Stop() cmd.exe /c shutdown.exe -r -d P:0:0 -t $startTime -f $Global:hash.Window.Close() }
