powershell - 用于从远程计算机中删除几个本地用户的 Powershell 脚本

Question

我正在尝试删除远程计算机上的本地用户帐户，其中主机名和用户名位于 csv 文件中。

下面的代码会起作用吗？

$hostdetail = Import-CSV C:\Users\oj\Desktop\Test\hosts.csv

ForEach ($item in $hostdetail) {
    $hostname = $($item.hostname)
    $username = $($item.username)
    $computer = $hostname

    #Test network connection before making connection and Verify that the OS Version is 6.0 and above
    If ((!(Test-Connection -comp $computer -count 1 -quiet)) -Or ((Get-WmiObject -ComputerName $computer Win32_OperatingSystem -ea stop).Version -lt 6.0)) {
        Write-Warning "$computer is not accessible or The Operating System of the computer is not supported.`nClient: Vista and above`nServer: Windows 2008 and above."
    }
    else {
        Invoke-Command -ComputerName $computer -ScriptBlock $scriptBlock
    }
}

$scriptBlock = {
    function Remove-UserProfile {
        Remove-LocalUser -Name $username
    }
    Remove-UserProfile
}

Answer 1

在调用命令之前调用$scriptblock。您应该通过-ArgumentsList参数传递$username 。$Args[0]将是-ArgumentsList中第一个参数的变量。

Powershell 从上到下读取。如果您将请求的对象或函数放在其当前正在读取的位置下方，则 powershell 不会知道它在那里。

$hostdetail = Import-CSV C:\Users\oj\Desktop\Test\hosts.csv

$scriptBlock = {
    Remove-LocalUser -Name $args[0]
}

ForEach ($item in $hostdetail) {
    $hostname = $($item.hostname)
    $username = $($item.username)
    $computer = $hostname

    #Test network connection before making connection and Verify that the OS Version is 6.0 and above
    If ((!(Test-Connection -comp $computer -count 1 -quiet)) -Or ((Get-WmiObject -ComputerName $computer Win32_OperatingSystem -ea stop).Version -lt 6.0)) {
        Write-Warning "$computer is not accessible or The Operating System of the computer is not supported.`nClient: Vista and above`nServer: Windows 2008 and above."
    }
    else {
        Invoke-Command -ComputerName $computer -ScriptBlock $scriptBlock -ArgumentList $username
    }
}
