递归复制文件期间的powershell错误检查 [英] powershell error checking during file copy with recursion

问题描述

我有一个程序可以递归复制文件夹和文件。
示例：

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

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

有时文件不会被复制。有没有一种方法可以进入递归内部或更好的方法，所以我可以在过程中而不是在病房之后启用某种错误检查。

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?

推荐答案

可以。例如，以下代码片段实际上将复制并检查每个文件是否存在错误。您还可以将自定义代码放在开头，以检查某些先决条件：

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."
    }
}
