windows - 将参数从命令行传递到 PowerShell 脚本

Question

有人好心地为我整理了一个 powershell 脚本。我是一个完全的编程业余爱好者。我一直无法联系到该用户进行我想要的更改，因此我自己亲自修改了脚本。

基本上我想传递一个参数，两个文件夹目录，以便脚本可以从源和目标生成哈希数据，然后比较它们。该脚本可以正常工作。但我想检查多个来源和目的地。

我做了一些谷歌搜索，发现以下应该有效:

powershell.exe -Command 'C:\temp\hashcheck.ps1' -SourceDir "D:\Temp\Public" -DestDir "D:\Temp\Public2"

其中“sourcedir”和“destdir”是我要传递的字符串的名称。但是当我从管理命令提示符运行它时，它给了我错误“意外的 token '-SourceDir'”

在 powershell 脚本中已经有几个参数参数，但我添加了“sourcedir”和“destdir”，如下所示:

            param (

                [Parameter(Mandatory=$True)]
                [String]
                $BaseDirectory,

                [Parameter(Mandatory=$True)]
                [String]
                $SourceDir,

                [Parameter(Mandatory=$True)]
                [String]
                $DestDir,

                [Parameter(Mandatory=$True)]
                [ValidateScript({!(Test-Path -path $_ -Type Leaf) })]
                [String]
                $OutputFilePath

            )

然后在这些命令中传递该参数:

        # Run this for Source
        Get-TreeCheckSum -BaseDirectory "$SourceDir" -OutputFilePath C:\temp\PublicSource.xml -Verbose

        # Run this for Destination
        Get-TreeCheckSum -BaseDirectory "$DestDir" -OutputFilePath C:\temp\PublicDestination.xml -Verbose

谢谢你的帮助。这可能是一个简单的解决方案，但正如我所说，我对 powershell 完全是业余爱好者。提前致谢。

编辑:这是完整的代码，也许会更有意义。我基本上想在分配给“BaseDirectory”的“#Run this for source”和“#Run this for Destination”部分下传递文件夹名称

        # Created by P33500k for fun..
        # Use at your own risk follow directions at end to run the commands
        function Get-TreeCheckSum {
            [CmdletBinding()]
            param (

                [Parameter(Mandatory=$True)]
                [String]
                $BaseDirectory,

                [Parameter(Mandatory=$True)]
                [ValidateScript({!(Test-Path -path $_ -Type Leaf) })]
                [String]
                $OutputFilePath


            )

            begin {
                # Define $results as an array of objects
                $results = @()


            }

                        'RelativePath' = ($file.fullname.substring($BaseDirectory.Length))
                    }
                    $results += $tempobj
                    $tempobj = $null
                }

尝试像这样直接调用脚本:

C:\temp\hashcheck.ps1 -SourceDir "D:\Temp\Public" -DestDir "D:\Temp\Public2"
