我已经在 Windows Server 2008（Powershell 版本 4）上运行了一个 robocopy 脚本，现在大约 6 个月没有出现任何问题。

我们最近不得不从这台机器上迁移以从 Windows Server 2019 (Powershell 5) 机器上启动相同的脚本。完全相同的脚本不再起作用，我不太确定问题出在哪里。脚本是：

# Run BCP Bat file to get list of folders that have changed in the past 12 days and save them to 
\\xxxx\xxxx\xxx\xxx\xxx.bat

# Select the starting directory to pull the CSV from.  The assumption is  that  the DB file can #be sent to a dedicated directory that just has only the CSV files 
$Filerecentdir = "\\ZZZ\Z\ZZZ\ZZZZZ\ZZZZ\ZZZZZZ"
#

# Filtering for only CSV files
$Filter = "*.csv"
#

# This PS command will search for the file with  the latest timestamp on it.  Coupling this with #the filter above, we turn $Filerecent into a variable consisting of the most recent CSV
$Filerecent = Get-ChildItem -Path $Filerecentdir -Filter $Filter | Sort-Object LastAccessTime -Descending | Select-Object -First 1
#

# I concatenate $Filerecentdir with the $Filerecent variable to form the full path to the CSV
$FullPath = Join-Path -path $Filerecentdir -ChildPath $Filerecent
#

# $roboSource variable uses import-csv cmdlet to parameterize the one (headerless) column that #the DB file creates
$roboSource = Import-Csv -Header @("a") -Path $FullPath
#

# Arbitrary directory that i'm using to  store the logs.  We'll change this to something on the #file server so it can be viewable
$logPath = "\\AAAA\A\AAAA\AAAA\AAAA\AAAA\"

#creates a folder to seperate weekly logs based off the output of the bat script
$weeklylogfolder = $Filerecent -replace '_.csv'
New-Item -ItemType Directory -Force -Path "$($logPath)$($weeklylogfolder)"
#

# For each loop to iterate over every single row in the CSV
Foreach($script in $roboSource)
{
    # I used the two below variables to replace the two last trailing '\' in each entry
    $prefix = $script.a -replace '\{.+'
    $suffix = $script.a.Substring($prefix.Length) -replace '\\', '_' #keeping the {} in the file #name.
    #$suffix = $script.a.Substring($prefix.Length) -replace '[{}]' -replace '\\', '_'
    #

    #$logFileName = $prefix + $suffix
    $logFileName = $suffix
    #

    # Same switches that we used
    #$StandardSwitches = "/copy:DAT /s /dcopy:DAT /V /L" #no copy
    $StandardSwitches = "/copy:DAT /s /dcopy:DAT /V" #Copy
    #

    # Creates the log file in the same format that we used, so one log file per entry
    $log = "/log:`"$($logPath)$($weeklylogfolder)\$($logFileName).log`""
    #

    # Iterates through each row to create the source and destination
    $FileSource = "$($script.a)"
    $FileDestination = "$($script.a)"
    #

    # used this to surround the certain variables with double quotes, otherwise Robo fails
    $RoboArgs = '"I:\{0}" "Z:\{1}" {2} {3}' -f 
                $FileSource, $FileDestination, $StandardSwitches, $log

    #
    Robocopy $RoboArgs
}

我似乎无法确定导致我所看到的问题的原因。我尝试单独运行脚本中的每个命令，当我这样做时，我注意到 $RoboArgs 变量似乎被切断，然后生成一个不完整的 $FileDestination

上面的 $RoboArgs 生成的输出与服务器 2008/Powershell 4 上的输出完全相同。但是，powershell 5 的处理方式似乎不同。有什么我做错了或需要添加才能正确处理吗？

编辑：

这是 $RoboArgs 在 Win2019/Powershell5 中定义的示例：

PS C:\> echo $RoboArgs
"I:\Fake-directory\Fake-directory\D\{DAFD6721-E854-46F3-B5CF-7EE1861348A6}\Fake\FakeDate" "Z:\Fake-Directory\Fake-Directory\D\{DAFD6721-E854-46F3-B
5CF-7EE1861348A6}\Responses\01182020" /copy:DAT /s /dcopy:DAT /V /log:"I:\FakeDirectory\FakeDirectory\Fake\Logs\Folders_Changed_20200118_21.1
\{DAFD6721-E854-46F3-B5CF-7EE1861348A6}_Responses_01182020.log"

它基本上切断了第一行结束的地方，并以相同的方式生成目的地：

PS C:\> Robocopy "I:\Fake-directory\Fake-directory\D\{DAFD6721-E854-46F3-B5CF-7EE1861348A6}\Fake\FakeDate" "Z:\Fake-Directory\Fake-Directory\D\{DAFD6721-E854-46F3-B
5CF-7EE1861348A6}\Responses\01182020" /copy:DAT /s /dcopy:DAT /V /log:"I:\FakeDirectory\FakeDirectory\Fake\Logs\Folders_Changed_20200118_21.1
\{DAFD6721-E854-46F3-B5CF-7EE1861348A6}_Responses_01182020.log"

编辑 2：将其与 Win2008/Powershell4 进行比较，如果有换行符，它实际上会在失败方面做同样的事情。我认为真正的问题是脚本如何尝试定义源和目标。在 2008/Powershell4 上，运行脚本会正确生成所有内容，包括正确的源、目标和日志文件。在 2019/Powershell5 上运行完全相同的脚本似乎会产生一个问题，即 Robocopy 如何定义这些路径，将 Source、Destination 和 Log 路径都放入源变量中，即使它不是这样定义的：

PS C:\> echo $FileSource
FakeDirectory\FakeDirectory\D\{DAFD6721-E854-46F3-B5CF-7EE1861348A6}\Responses\01182020

PS C:\> echo $FileDestination
FakeDirectory\FakeDirectory\D\{DAFD6721-E854-46F3-B5CF-7EE1861348A6}\Responses\01182020

PS C:\> echo $log
/log:"I:\FakeDirectory\FakeDirectory\FakeDirectory\Logs\Folders_Changed_20200118_21.1\{DAFD6721-E854-46F3-B5CF-7EE1861348A6}_Responses_01182020.log"

PS C:\> echo $StandardSwitches
/copy:DAT /s /dcopy:DAT /V
