Powershell脚本获取目录树的全名

Question

I'm trying to get an output of the FullName of a Folder of each level from a specific directory tree.

I want to get an output like:

C:\
C:\dir1
C:\dir1\dir2
C:\dir1\dir2\dir3

The thing is that the directory has to be specific... like the directory part between C:\\ and C:\\dir1\\dir2\\dir3

Like a start path and end path, any thoughts?

Answer 1

For PowerShell v3 or later:

Get-ChildItem C:\dir1 -Directory -Recurse |
  Select-Object -ExpandProperty FullName

For older versions:

Get-ChildItem C:\Dir1 -Recurse |
  Where-Object { $_.PSIsContainer } |
  Select-Object -ExpandProperty FullName

Answer 2

Try this:

$Path = 'C:\dir1\dir2\dir3'

$Folders = $Path -Split "\\"
$Folders | % { $i = 0 } { $Folders[0..$i] -Join "\" -Replace ":$", ":\"; $i++ } 

Result:

C:\
C:\dir1
C:\dir1\dir2
C:\dir1\dir2\dir3
