我有这个目录结构在C:temp
a
|
+--aa (folder)
| +
| +-- subfile1.zip
|
+- file.txt
z
|
+--hh (folder)
| |
| +-- subfile2.txt
|
+- file2.txt
c
|
+--kku (folder)
| |
| +-- subfile3.txt
|
+- file3.txt
我想移动到C:temp只有文件在这些路径
C:tempa
C:tempz
C:tempc
但是我不想从这些路径中移动文件
C:tempaaa
C:tempzhh
C:tempckku
我不太明白如何设置目录的级别。我试试这个
$rootPath = "C:temp"
Get-ChildItem -Path $rootPath -Recurse -File | ForEach-Object {
$filePath = $_.FullName
$fileName = $_.Name
$folderPath = $_.DirectoryName
if ($folderPath -notmatch "^$rootPath\[a-z]\.*\hh$" -and $folderPath -notmatch "^$rootPath\[a-z]\.*$" -and $folderPath -ne $rootPath) {
Move-Item -Path $filePath -Destination "$rootPath$fileName"
}
}
我想我弄乱了正则表达式，但我想知道如果这是问题
首先，您使这项工作过于复杂。
其次，在代码中没有任何地方设置深度，这是使用Get-ChildItemcmdlet的开关。

NAME
Get-ChildItem
SYNOPSIS
Gets the items and child items in one or more specified locations.
...
-------- Example 8: Get items using the Depth parameter --------
Get-ChildItem -Path C:Parent -Depth 2

The `Get-ChildItem` cmdlet uses the Path parameter to specify C:Parent .
The Depth parameter specifies two levels of recursion.
`Get-ChildItem` displays the contents of the
directory specified by the Path parameter and the two levels of subdirectories.

如果您只在特定目录之后，那么只针对这些目录，不使用-Recurse开关，您不应该担心子目录。
采用-Depth方法，您根本不需要RegEx。为了避免这样的调试麻烦，总是一步一步地编写和处理代码。在进入下一行之前，确保你在每一行都得到了你所期望的。它几乎消除了调试头痛和不必要的代码工作。
例如:
# Create the directory tree and file structure to test
Clear-Host
@(
'a',
'z',
'c',
'aaa',
'zhh',
'ckku'
) |
ForEach-Object {
New-Item -Path 'D:tempFolderTest' -ItemType Directory -Name $PSItem
Start-Sleep -Seconds 1
If ($PSItem -Notmatch '\')
{
New-Item -Path "D:tempFolderTest$PSItem" -ItemType File -Name "$PSitem.txt"
Start-Sleep -Seconds 1
}
Else
{
New-Item -Path "D:tempFolderTest$PSItem" -ItemType File -Name "$(($PSitem -split '\')[-1]).txt"
Start-Sleep -Seconds 1
