执行您所要求的操作的规范方法可能是使用here-string并通过format operator（-f）插入特定值：

foreach ($server in $testServers) {
    @'
$computer = '{0}'

Invoke-Command -ComputerName $computer -ScriptBlock {
    Set-ExecutionPolicy Bypass
    Find-Module PSWindowsUpdate | Install-Module -Force | Import-Module -Force
}

$updatesCount = (Get-WindowsUpdate -ComputerName $computer).Count

while ($updatesCount -gt "0") {
    psexec \\$computer -s 'powershell.exe "Install-WindowsUpdate -Confirm:$false -IgnoreReboot"'
    Restart-Computer -ComputerName $computer -Force -Wait
    $updatesCount = (Get-WindowsUpdate -ComputerName $computer).Count
}
'@ -f $server | Set-Content -Path "D:\tools\windows updates\uscripts\${server}_wu.ps1"
}

然而，我认为编写一个参数化脚本并使用相应的计算机名称调用它可能比为每台计算机创建一个脚本更合适：

[CmdletBinding()]
Param(
    [Parameter(Mandatory=$true)]
    [string]$Computer
)

Invoke-Command -ComputerName $Computer -ScriptBlock {
    Set-ExecutionPolicy Bypass
    Find-Module PSWindowsUpdate | Install-Module -Force | Import-Module -Force
}

$updatesCount = (Get-WindowsUpdate -ComputerName $Computer).Count

while ($updatesCount -gt "0") {
    psexec \\$Computer -s 'powershell.exe "Install-WindowsUpdate -Confirm:$false -IgnoreReboot"'
    Restart-Computer -ComputerName $Computer -Force -Wait
    $updatesCount = (Get-WindowsUpdate -ComputerName $Computer).Count
}

调用：

PS> **script.ps1 -Computer FOO**

好吧-所以我不知道如何操纵我的字符串，并最终解决它像这样.任何更短、更简单的答案都是绝对受欢迎的（请注意，脚本的其余部分也发生了一些变化）

foreach ($server in $testServers) {

    New-Item -ItemType File -Name "$($server)_wu.ps1" -Path "\\VILV12ICTSCRIPT\d$\windowsupdates\uscripts"

    $value = '

    $computer = $PSCommandPath
    $computer = $computer.Split("`\")[3]
    $computer = $computer.Split("_")[0]

    Invoke-Command -ComputerName $computer -ScriptBlock {

        Set-ExecutionPolicy Bypass
        Find-Module PSWindowsUpdate | Install-Module -Force | Import-Module -Force

    }

    $updatesCount = (PsExec.exe \\$computer -s "powershell.exe "Get-WindowsUpdate"").Count

    while ($updatesCount -gt "0") {

        psexec \\$computer -s "powershell.exe "Install-WindowsUpdate -Confirm:`$false -IgnoreReboot""
        Restart-Computer -ComputerName $computer -Force -Wait
        $updatesCount = (PsExec.exe \\$computer -s "powershell.exe "Get-WindowsUpdate"").Count

    }

    Write-Host "No more updates available for $($computer)" -BackgroundColor DarkGreen

    '

    Set-Content -Path "\\VILV12ICTSCRIPT\d$\windowsupdates\uscripts\$($server)_wu.ps1" -Value $value

}

要生成的脚本和生成的脚本都像charms（^^，）一样工作

我只是用了一个刻度线来避开美元符号。当它写入文件时，它不带刻度线。
