Generating array from multiple folder paths - powershell

Question

Alright, I am confusing my self on how to get this to work. I have several folder locations that have multiple sub-folders. These sub-folders are all named after hosts on our network. So I am working on a script to validate the contents of the folders for auditing purposes. I can not seem to generate a usable list that has the system name derived from the folder name and the full path name. I.G.
Name Path
---- ----
system1 \\path\rootfolder1\system1
system2 \\path\rootfolder1\system2
system3 \\path\rootfolder2\system3
I get the root folders from a CSV file as the folders are not all in one location and I do not need to use every folder time I run the report.
#Path to folder repository. Folder names must be the systems host name.
$list_paths = (Import-Csv 'C:\CVS\path\Paths.csv').path
#list arrays
$list = #()
$list2= #()
#Counters
$p_count = 0
$l_count = 0
#Generates array (list) of folder paths
Foreach ($p1 in $list_paths){
$l_count ++
$listx1 = Get-ChildItem $p1 | Where-Object {$_.PSIsContainer} | Foreach-object {$_.FullName}
$list += $listx1
}
#Generates array (list) of system names from folder
ForEach ($p2 in $list){
$p_count ++
Write-Host $p2
$listx2 = split-path -path $p2 -leaf
$list2 += $listx2
}
$Output = New-Object PSObject -Property #{
"Name" = $list
"Path" = $list2
}
Write-Host ($Output | Format-table | Out-String)
Write-Host Number of root folders
Write-Host $l_count
Write-Host Number of host folders
Write-Host $p_count'
So when I run the script $output produces this instead of the format I want above.
Name
----
{\\path\rootfolder1\system1, \\path\rootfolder2\system2, \\path\root...}
I know I am doing something wrong but I can seem to figure out what.

You only create one object with every name and every path as the property-values, not one "Name + Path"-object per system-folder like your first example. Also, you're mixing your lists, so the paths ended up in the Name-property.
Try moving the New-Object job inside a foreach-loop that processes the system-folders. I'd also recommend readable variable-names.
#Path to folder repository. Folder names must be the systems host name.
$rootpaths = (Import-Csv 'C:\CVS\path\Paths.csv').path
#Systems found
$systems = #()
#Find system-folders inside each root
Foreach ($root in $rootpaths){
Get-ChildItem $root | Where-Object { $_.PSIsContainer } | Foreach-object {
#Foreach system-folder, generate a result object
$systems += New-Object PSObject -Property #{
#No need to split the path. The object already contains the leaf-name in the Name-property
"Name" = $_.Name
"Path" = $_.FullName
}
}
}
#No need for write-host if you're writing everything as strings anyways
$systems | Format-table | Out-String
"Number of root folders: $($rootpaths.Count)"
"Number of host folders $($systems.Count)"
As mentioned by #TheMadTechnician, if use the pipeline for what it's worth, this can actually be shortened down to:
#Path to folder repository. Folder names must be the systems host name.
$rootpaths = (Import-Csv 'C:\CVS\path\Paths.csv').path
#Find system-folders inside each root
$systems = Get-ChildItem -Path $rootpaths | Where-Object { $_.PSIsContainer } | Select-Object Name, FullName
#Or this if you have Powershell 3.0+
#$systems = Get-ChildItem -Path $rootpaths -Directory | Select-Object Name, FullName
#No need for write-host if you're writing everything as strings anyways
$systems | Format-table | Out-String
"Number of root folders: $($rootpaths.Count)"
"Number of host folders $($systems.Count)"
