有沒有辦法用多個不同的路徑回圈“測驗路徑”（PowerShell）

$applicationArray = $filezilla = "C:\Program Files\FileZilla FTP Client\filezilla.exe", $notepad = "C:\Program Files\Notepad  \notepad  .exe", $cisco = "C:\Program Files (x86)\Cisco\Cisco AnyConnect Secure Mobility Client\vpnui.exe", $adobe = "C:\Program Files (x86)\Adobe\Acrobat 9.0\Acrobat\Acrobat.exe"

foreach ($application in $applicationArray)
    {
        Test-path

     if (Test-path) 
     {
         Write-Host "Folder Exists"
       }
     else
     {
         Write-Host "Folder Does Not Exist"
     }
   }

我正在嘗試撰寫一個腳本來檢查是否使用“測驗路徑”命令安裝了上述程式。當我在單獨的“if”陳述句中運行它們時，它們都可以作業，但我希望回圈它，以便我可以壓縮腳本以盡可能高效。但是當我嘗試運行上述內容時，出現以下錯誤：

看起來您正在嘗試創建哈希表，但語法不太正確。讓我們像這樣嘗試，

$apps = @{
  filezilla = "C:\Program Files\FileZilla FTP Client\filezilla.exe"
  notepad = "C:\Program Files\Notepad  \notepad  .exe"
  cisco = "C:\Program Files (x86)\Cisco\Cisco AnyConnect Secure Mobility Client\vpnui.exe"
  adobe = "C:\Program Files (x86)\Adobe\Acrobat 9.0\Acrobat\Acrobat.exe"
}

要使用哈希表值，請遍歷其鍵并按鍵值訪問每個專案，如下所示，

foreach($k in $apps.keys) {
  "Testing path for {0} -> {1}: {2}" -f $k, $apps[$k], $(test-path $apps[$k])
}
# output

Testing path for adobe -> C:\Program Files (x86)\Adobe\Acrobat 9.0\Acrobat\Acrobat.exe: False
Testing path for notepad -> C:\Program Files\Notepad  \notepad  .exe: True
Testing path for cisco -> C:\Program Files (x86)\Cisco\Cisco AnyConnect Secure Mobility Client\vpnui.exe: False
Testing path for filezilla -> C:\Program Files\FileZilla FTP Client\filezilla.exe: False

這不起作用：

$applicationArray = $filezilla = "C:\Program Files\FileZilla FTP Client\filezilla.exe", $notepad = "C:\Program Files\Notepad  \notepad  .exe", $cisco = "C:\Program Files (x86)\Cisco\Cisco AnyConnect Secure Mobility Client\vpnui.exe", $adobe = "C:\Program Files (x86)\Adobe\Acrobat 9.0\Acrobat\Acrobat.exe"

你可以做一組檔案路徑來驗證，例如：

$paths = @(
   "C:\Program Files\FileZilla FTP Client\filezilla.exe",
   "C:\Program Files\Notepad  \notepad  .exe"
)

完成后，您可以遍歷陣列并運行 test-path foreach 元素，例如：

foreach ($path in $paths){
   If (Test-path -path $path){
      write-host "Folder Exists"
   }
   Else {
      Write-Host "Folder Does Not Exist"
   }
}

您可以使用哈希表來提高可讀性并遍歷每個測驗路徑。

@{
    filezilla = "C:\Program Files\FileZilla FTP Client\filezilla.exe"
    notepad   = "C:\Program Files\Notepad  \notepad  .exe"
    cisco     = "C:\Program Files (x86)\Cisco\Cisco AnyConnect Secure Mobility Client\vpnui.exe"
    adobe     = "C:\Program Files (x86)\Adobe\Acrobat 9.0\Acrobat\Acrobat.exe"
}.GetEnumerator() | % {
    if (Test-Path -LiteralPath $_.Value) {
        '{0,-10} - Exists.' -f $_.Key
    }
    else {
        '{0,-10} - Not Found.' -f $_.Key
    }
}

# Results
adobe      - Not Found.
notepad    - Not Found.
cisco      - Exists.
filezilla  - Not Found.

我喜歡 vonPryz 的方法，所以我更新了我的方法來模仿他/她的方法。只是將條件陳述句合并到字串格式值中，本質上是相同的。

'{0,-10} - {1}' -f $_.Key, $(
    if (Test-Path -LiteralPath $_.Value) { 'Exists' } else { 'Not Found' }
)
