PowerShell array issue_

Question

I have been writing a powershell script to solve a problem, the utility of the script may baffle some but I have a use in mind.

The aim of the script is to create a new directory in the temp folder that mirrors the name of the folder in the parent folder but with the script as it is the newly created folder names in the temp folder have the following text around them @{Name=FOLDERNAME} how can I edit the script just to get FOLDERNAME?

$dirs = @(Get-ChildItem -Path C:\Users\LTGoldman\Desktop\keys -Recurse -Directory -Force -ErrorAction SilentlyContinue | Select-Object Name)
for($i=0; $i -lt $dirs.length;$i++)
    {
        New-Item -Path "C:\Users\LTGoldman\Desktop\keys\temp" -Name $dirs[$i] -ItemType "directory"
        Move-Item -Path .\*.tar.gz -Destination C:\Users\LTGoldman\Desktop\keys\temp\$dirs[$i]
    }

Changed to:

$dirs = @(Get-ChildItem -Path C:\Users\LTGoldman\Desktop\keys -Recurse -Directory -Force -ErrorAction SilentlyContinue | Select-Object Name)
for($i=0; $i -lt $dirs.length;$i++)
    {
        New-Item -Path "C:\Users\LTGoldman\Desktop\newkeys" -Name $dirs[$i].Name -ItemType "directory"
        Move-Item -Path "C:\Users\LTGoldman\Desktop\keys\"+$dirs[$i]+"\*.tar.gz" -Destination C:\Users\LTGoldman\Desktop\newkeys\$dirs[$i].Name
    }

I am not sure how to concatenate the Move-Item line properly?

At first glance, doing this will solve your problem $dirs[$i].Name (on both lines) or just do Select-Object -ExpandProperty Name — Santiago Squarzon

You also need to correct this Move-Item -Path .\*.tar.gz, which files are these? The ones that are in each $dirs[$i] ? — Santiago Squarzon

Brilliant, that seems to have done the trick, the folders are empty at the moment but I will look into this first. If I have further difficulties, i'll post back. — Myron Goldman

Normally you would use a foreach loop to handle this, it also looks cleaner:

$sourceFolder = 'C:\Users\LTGoldman\Desktop\keys'
$destinationFolder = 'C:\Users\LTGoldman\Desktop\keys\temp'

foreach($folder in Get-ChildItem $sourceFolder -Directory -Recurse)
{
    New-Item -Path $destinationFolder -Name $folder.Name -ItemType Directory
}

Since you're using -Recurse you might also will need to handle collision of folders:

$newFolder = Join-Path $destinationFolder -ChildPath $folder.Name
if(Test-Path $newFolder)
{
    Write-Warning "$($folder.Name) already exists in $destinationFolder. Skipping."
    continue
}

Another way to handle collision would be with a try catch, just assume there is no collision and if there is, skip it:

try
{
    New-Item -Path $destinationFolder -Name $folder.Name -ItemType Directory
}
catch
{
    Write-Warning "$($folder.Name) already exists in $destinationFolder. Skipping."
}
