Copy-Item 应该创建目标目录结构吗? [英] Should Copy-Item create the destination directory structure?

问题描述

我正在尝试将文件复制到新位置，以保持目录结构.

I'm trying to copy a file to a new location, maintaining directory structure.

$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'

推荐答案

-recurse 选项仅在源是目录时创建目标文件夹结构.当源是一个文件时，Copy-Item 期望目标是一个已经存在的文件或目录.您可以通过以下几种方法解决此问题.

The -recurse option only creates a destination folder structure if the source is a directory. When the source is a file, Copy-Item expects the destination to be a file or directory that already exists. Here are a couple ways you can work around that.

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

Option 2: 'Touch' the file first and then overwrite it

$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
