Question

你们中的几个人（特别是谢谢！）昨天帮助了我，我设法提出了多个脚本，现在我们将它们合并为一个。

问题是我已将它们全部放入“函数”中，并且一个函数依赖于对修补程序的成功检查 - 如果未安装此修补程序，则脚本必须在那里停止然后 - 这是第一次检查脚本的确如此。如何获取下一个函数来调用修补程序函数的成功输出？

此外我不知道如何调用这些函数 - 即在底部我将函数的名称放在一行之后但最终循环遍历！

希望有人可以提供帮助。

要使用函数Service中的修补程序，您应该将修补程序返回给变量。该功能如下所示：

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

}

然后函数调用将是：

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

函数Robocopy不需要$hotfix1作为参数，因为它不会在函数的任何地方使用。

Robocopy函数可能正在循环，因为对robocopy.exe的调用与Robocopy函数相同;尝试将“.exe”添加到robocopy.exe调用。命名功能以准确反映其目的非常重要。 Service可以是Get-HotFixKB979808，Robocopy可以是Start-MyRobocopy

说了这么多，既然你的功能做了非常具体的事情，他们真的不需要成为他们自己的功能。您可以通过让它们接受参数来将它们更改为可重用。
