检查.ISO是否已经安装在PowerShell中，如果没有安装

Question

我有一个从旧游戏磁盘复制的ISO文件。但为了让我玩这个游戏，我必须安装ISO。 我写了一个小批处理文件，该文件运行.ps1 PowerShell文件来挂载ISO，然后运行EXE在挂载后启动游戏。我的问题是，如果我多次运行脚本，它将再次安装ISO。

我要检查，如果ISO连接，安装它，如果它不是，或运行EXE，如果它是。

这是我必须安装ISO：
批次。

ECHO "Mounting Stunt Track Driver" 

@ECHO off 

Powershell.exe -executionpolicy remotesigned 
-File "C:\Users\Allen\Documents\Games\Hot Wheels Stunt Track 
Driver\setup\hot98\mount.ps1" 

start /d "C:\Users\Allen\Documents\Games\Hot Wheels Stunt Track 
Driver\setup\hot98" stunt.exe 

PowerShell的

#mounts the image 
Mount-DiskImage -ImagePath "C:\Users\Allen\Documents\Games\Hot Wheels Stunt 
Track Driver\setup\hot98\HotwheelsStuntTrack.iso" 

Answer 1

如果它没有安装这个片段将只安装图像：

if(!(get-DiskImage -ImagePath C:\testshare\97001.ISO).Attached){ 
Mount-DiskImage -ImagePath C:\testshare\97001.ISO 
} 

Answer 2

为了配合阿济斯的答案，特别提到一个错误我以前打：

$imagePath = "the path to your .ISO file" 

$mount = Mount-DiskImage -ImagePath $imagePath -PassThru 
$driveLetter = ($mount | Get-Volume).DriveLetter 
$drive = $driveLetter + ":\" 

# PowerShell bug workaround 
# Forces PowerShell to update drive info for its providers 
# Not doing so makes Test-Path fail on freshly mounted drives 

Get-PSDrive > $null 

$setupPath = $drive + "the path to your exe on the mounted drive" 
$setupArgs = "your .exe args" 

if (!(Test-Path $setupPath)) { 
    # ... Something went wrong ... 
} else { 
    $process = Start-Process $setupPath -ArgumentList $setupArgs -Wait -PassThru 
    # You can check $process.ExitCode here  
}
