Powershell 如何合并多个脚本并使用函数显示输出

你们中的一些人（特别是Shay！）昨天帮助了我，我已经想出了多个脚本，现在正在将它们合并成一个

问题是，我已经将它们全部放入“函数”中，其中一个函数依赖于对修补程序的成功检查-如果没有安装修补程序，则脚本必须立即停止，然后-这是脚本执行的第一次检查。如何让下一个函数调用修补程序函数的成功输出

我也不知道如何调用函数——也就是说，在底部我把函数的名称放在一行之后，但最后循环了一次又一次

希望有人能帮忙

服务中找到的修补程序，应将修补程序返回到变量。函数如下所示：

Function Service
{
    Write-Host "=================================="
    Write-Host "Checking Service Installation"
    Write-Host "=================================="

    write-host "This will check if Hotfix KB979808 is installed." -ForegroundColor Black -BackgroundColor Cyan
    write-host "This is required for Windows Server 2008 R2 Robocopying"  -ForegroundColor Black -BackgroundColor Cyan
    Write-Host ""

    # This will return any output.
    Get-HotFix -id KB979808 -ErrorAction SilentlyContinue

}

那么函数调用将是：

$hotfix = Service
if($hotfix) {
    Robocopy
}
else {
    # This will exit the script.
    return
}

函数
Robocopy
不需要
$hotfix1
作为参数，因为它不在函数中的任何位置使用

Robocopy
函数可能正在循环，因为对Robocopy.exe的调用与您的
Robocopy
函数相同；请尝试添加“.exe”“调用robocopy.exe。命名函数以准确反映其用途非常重要。
服务
可以是
Get-hotfix KB979808
，
robocopy
可以是
Start myrobocy

话虽如此，由于你的函数做了非常具体的事情，它们真的不需要是它们自己的函数。你可以通过让它们接受参数来更改它们，使其更易于重用。
非常棒！非常感谢这一点-我更改了脚本并运行了它，一切都很好。一个问题-如何将脚本更改为accept参数？…可能对此有一个了解..您可以接受诸如，
函数MyRobocopy（$Sorce，$Target）之类的参数{robocopy$Source$Target/b/e/copyall/r:1/xd dfsrprivate/log:$Output/tee
。您可以像
myrobocy C:\Temp\MyFolder D:\Temp\MyFolder
一样调用它。有关函数的详细信息，请参阅
有关函数的帮助。
