使用递归进行文件复制期间的powershell错误检查

发布于 2024-09-24 20:23:32 字数 202 浏览 3 评论 0原文

我有一个程序可以递归地复制文件夹和文件。示例：

Copy-Item -path "$folderA" -destination "$folderB" -recurse

有时文件不会复制。有没有办法“步入递归”或更好的方法来做到这一点，这样我就可以在过程中而不是事后启用某种错误检查。甚至可能进行测试路径并提示重新复制？

I have a program that copies folders and files recursively.
example:

Copy-Item -path "$folderA" -destination "$folderB" -recurse

Sometimes the files do not copy. Is there a way to "step inside the recursion" or a better way to do it, so I can enable some kind of error checking during the process rather than after wards. Possibly even do a Test-Path and prompt for a recopy?

你可以。例如，以下代码片段将实际复制并检查每个文件是否存在可能的错误。您还可以将自定义代码放在开头来检查一些先决条件：

get-childItem $source -filter *.* | foreach-object {
    # here you can put your pre-copy tests...

    copy-item $_.FullName -destination $target -errorAction SilentlyContinue -errorVariable errors
    foreach($error in $errors)
    {
        if ($error.Exception -ne $null)
        {
            write-host -foregroundColor Red "Exception: $($error.Exception)"
        }
        write-host -foregroundColor Red "Error: An error occured during copy operation."
    }
}

You can. For example the following code snippet will actually copy and check each file for possible errors. You can also put your custom code at the beginning to check for some prerequisites:

get-childItem $source -filter *.* | foreach-object {
    # here you can put your pre-copy tests...

    copy-item $_.FullName -destination $target -errorAction SilentlyContinue -errorVariable errors
    foreach($error in $errors)
    {
        if ($error.Exception -ne $null)
        {
            write-host -foregroundColor Red "Exception: $($error.Exception)"
        }
        write-host -foregroundColor Red "Error: An error occured during copy operation."
    }
}
