PowerShell 常用命令

1. 获取某文件夹下所有文件的 MD5

Get-ChildItem -Path "E:\" -Recurse | ForEach-Object {
    if (-not $_.PSIsContainer) {
        $hash = Get-FileHash -Path $_.FullName -Algorithm MD5
        Write-Output "$($hash.Hash)  $($hash.Path)"
    }
}

2. 获取文件的产品版本

(Get-Item "YOUR_FILE_PATH").VersionInfo | Select-Object ProductVersion

PS C:\Users\UserName> (Get-Item "YOUR_FILE_PATH").VersionInfo | Select-Object ProductVersion

ProductVersion
--------------
2.0.8682.24152

3. 批量给文件设置控制权限

$FolderPath = "C:\path\to\folder"
$AccessRule = New-Object System.Security.AccessControl.FileSystemAccessRule(
    "NT SERVICE\MSSQLSERVER", 
    "FullControl", 
    "Allow"
)

$FolderAcl = Get-Acl $FolderPath
$FolderAcl.SetAccessRule($AccessRule)
Set-Acl $FolderPath $FolderAcl

Get-ChildItem $FolderPath -Recurse | ForEach-Object {
    $FilePath = $_.FullName
    $FileAcl = Get-Acl $FilePath
    $FileAcl.SetAccessRule($AccessRule)
    Set-Acl $FilePath $FileAcl
}
