What I want to do is copy a directory that exists in multiple parent directories, to a destination while preserving the \Parent\child structure. The source directories are versioned software releases, and the directory that I want contains hot-fixes for each of those versions.

Source directory structure

\Releases\app_26.6.1.123\Patch\
\Releases\app_26.6.2.456\Patch\
etc etc

The last two numbers change, but the format is always #.## or #.###, with the first # incrementing from 1 to 7.

And what I'm trying to do is something like this:

copy \Release\app_26.6.[1-7].*\Patch\ to C:\Temp\eureka\app_26.6.[1-7].*\Patch\

I think that I'll have to use a for loop iteration, but my brain is hurting trying to think of a way to do this in powershell; and that's why I'm here.

This post is pretty close to what I want to do, but wrong platform: Copying multiple directories into multiple destination directories

Thank you

I'm assuming you have multiple destinations per source patch? Try something like this where you wildcard up the version number in the name:

Foreach ($src in (Get-Item "\Releases\app_*\Patch")) {

  # Split off the last version number on the parent folder
  $baseVersion = ($src.parent.name -split '\.')[0..2] -join '.'

  # Get each destination folder using * wildcard
  $destinations = Get-Item "c:/Temp/eureka/$baseVersion*/"

  # Copy folders
  Foreach ($dst in $destinations) {
    Copy-Item $src.FullName $dst.FullName -Recurse 
  }

}

This should create the following source and destination structure:

# src
\Releases\app_26.6.1.123\Patch\1
\Releases\app_26.6.2.456\Patch\2

# dst
c:/Temp/eureka/app_26.6.1.100/Patch/1
c:/Temp/eureka/app_26.6.1.200/Patch/1

c:/Temp/eureka/app_26.6.2.300/Patch/2
c:/Temp/eureka/app_26.6.2.400/Patch/2

If you don't want a wildcard but specifically need [1-7], you can use regex:

$destinations = Get-Item "c:/Temp/eureka/*/" |
  Where Name -match "$baseversion.[1-7]"
