powershell - Copy-Item 是否应该创建目标目录结构？

Question

我正在尝试将文件复制到新位置，同时维护目录结构。

$source = "c:\some\path\to\a\file.txt"
destination = "c:\a\more\different\path\to\the\file.txt"

Copy-Item  $source $destination -Force -Recurse

但是我得到一个DirectoryNotFoundException:

Copy-Item : Could not find a part of the path 'c:\a\more\different\path\to\the\file.txt'

Answer 1

如果源是目录，则 -recurse 选项仅创建目标文件夹结构。当源是文件时，Copy-Item 期望目标是已存在的文件或目录。您可以通过以下几种方法来解决这个问题。

选项 1:复制目录而不是文件

$source = "c:\some\path\to\a\dir"; $destination = "c:\a\different\dir"
# No -force is required here, -recurse alone will do
Copy-Item $source $destination -Recurse

选项 2:先“触摸”文件，然后覆盖它

$source = "c:\some\path\to\a\file.txt"; $destination = "c:\a\different\file.txt"
# Create the folder structure and empty destination file, similar to
# the Unix 'touch' command
New-Item -ItemType File -Path $destination -Force
Copy-Item $source $destination -Force
