PowerShell腳本，如果/否則使用測試路徑，如果/否則不正常工作時False

Question

完全公開，我是使用Powershell的新手，我正在研究測試38個excel報告是否在（如Excel-Advanzia-Outages 2015年9月18日），將它們複製到另一個文件夾作爲備份，在另一個Excel工作簿中運行宏（將報表按照日期），最後從原始文件夾中刪除38個報告。

我從其中一個報告中更改/刪除了日期，以便它將返回false來測試將要發生的情況，但它仍然試圖執行IF語句中的代碼。如果所有報告的格式正確，一切都可以正常工作。

我很想聽聽關於如何解決錯誤的一些反饋，或者如果可能有更好，更動態的方式來編碼。謝謝！

這裏是我到目前爲止的代碼：

# Declares variable $a as today's date and will add 2 days in "dd MMM yyyy" formatting (Adding 2 days because this will be set up to run on Wednesday and checks for files that have Friday's date) 
$a = "{0:dd MMM yyyy}" -f (get-date).AddDays(2) 

# Verifies each Excel file is correctly formatted with upcoming Friday's date formatted as "dd MMM yyyy" at end of file. If true, code inside if statement is executed.

Answer 1

這是因爲有些值返回true。你應該考慮做的是將所有路徑存儲在一個數組變量中，然後通過foreach循環一次一個地測試和處理每個路徑。所以它看起來更像是這樣的：

$Paths = "C:\Users\mathill\Desktop\Outages\Excel-Advanzia-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-AIB-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-American-Express-Corp-Srvcs-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-Amex-Central-Europe-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-Arcot-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-B+S-Card-Service $a.xls","C:\Users\mathill\Desktop\Outages\Excel-Bank-of-America-Asia-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-Bank-of-America-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-Barclays-Commercial-Card-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-BOI-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-C-Card-S-p-A-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-CCUK Finance-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-CMC-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-COBE-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-Degussa-Bank-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-Deutsche-Bank-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-Elavon-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-Home-Retail-Group-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-IE-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-ING-CPS-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-JPMC-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-KBC-Bank-Ireland-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-Lloyds-TSB-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-Metro-Bank-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-NBS-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-PayPal-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-Prime-Carrefour-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-PTSB-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-Rabo-Bank-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-RBSG-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-RSA-Cyota-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-Swisscard-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-Telrock-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-Tesco-Bank-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-TSYS-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-Virgin-Money-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-Wells-Fargo-Outages $a.xls","C:\Users\mathill\Desktop\Outages\Excel-WEX-Outages $a.xls") -eq $true) 

Foreach ($Path in $Paths) 
{ 
    #skips to next item in array if path not found (continue) 
    If (! (Test-path $Path)) 
    {Continue} 

    #rest of code goes here 
} 

或者，如果這裏的要求是，繼續，你可以確認，這樣之前存在的所有38路：

$Tests = test-path 'c:','c:\windows','c:\dontexist' 
If ($Tests -contains $False) 
{'path missing';return}
