無法在Powershell腳本中使用Get-Content尾部中斷

Question

我有蝙蝠腳本，在txt文件中寫了幾行。

set logfile=D:\my_job\out.txt
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo completed >>%logfile%
echo completeD >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%
echo ***Completed*** >>%logfile%
echo wwe >>%logfile%
echo wwe >>%logfile%

而且我有腳本可以停止執行我的工作，如果我看到***Completed***

Get-Content D:\my_job\out.txt –Wait | ForEach-Object {$_ ; if($_ -eq "***Completed***"){break} }

但這並不能阻止我的工作執行。 另外，我嘗試了這個：

Get-Content D:\my_job\out.txt –Wait | ForEach-Object {$_ ; if($_ -Match "***Completed***"){break} }

在輸出中，我看到：

parsing "***Completed***" - Quantifier {x,y} following nothing.
At C:\Users\jenkins\AppData\Local\Temp\jenkins4007901642048080451.ps1:1 char:138
+ ... t -Wait | ForEach-Object {$_ ; if($_ -Match "***Completed***"){break} ...
+                                       ~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : OperationStopped: (:) [], ArgumentException
    + FullyQualifiedErrorId : System.ArgumentException

您能幫我嗎，我該如何解決這個問題？

Answer 1

此命令將在行的末尾添加一個空格：

 echo ***Completed*** >>%logfile%

因此您的支票$_ -eq "***Completed***"將失敗。

刪除echo中的空格或在比較字符串中添加空格。

關於帶有-match的錯誤：它使用正則表達式操作，並且由於使用* ， ***Completed***是不正確的正則表達式。
