Powershell script to find file age on multiple shares - arrays

I'm working on a powershell script to read file attributes filtered by CreationTime on multiple shares. The scripts works, sporadically. It works great when I use a single path but I get mixed results when I add the folders paths to an array. The most disturbing result is when it successfully find and reads all path and then includes everything under c:windows\system32. Same anomaly when shares are empty.
So what I want to accomplish is:
Read list of Shares
Read each share content filtered by 'CreationTime' and 'Archive' attributes.
Save results to a csv file.
if file not empty, write results to event log.
here is my testing code
$Date=(Get-Date).AddHours(-3)
$FolderList = "C:\Software\Scripts\FolderList.txt"
$Folders = get-content $Folderpath
$Filepath = "C:\Software\Scripts"
$filename = "$Filepath\" + $timer + "OldFiles.csv"
foreach ($Folder in $Folders)
{
Get-ChildItem -Path $Folder -Recurse -Force | Where-Object { $_.CreationTime -lt $Date -and $_.Attributes -eq "Archive"} | Select Attributes, CreationTime, Fullname | Export-Csv -Path $filename -NoTypeInformation
}
if ( (get-childitem $filename).length -eq 0 )
{
exit
}
else{
#Write to OpsMgr Log
$Message = get-content $filename
Write-EventLog -LogName "Operations Manager" -Source "Health Service Script" -EventID 402 -EntryType Information -Message "Old files found. $Message"
}

Powershell array failing because of "Copy-Item : Illegal characters in path."

I have a specific usecase where I need to identify if files from a list exist, and if so, copy them to a separate location with the relevant file structure kept. I need to keep my list of targets in the same script.
I believe my issue is something to do with the way the data inside isn't being parsed correctly due to ":" for drive letters, but I'm unsure of how to get round this issue.
As you can see from the code below, I attempted to fix the issue by ignoring the drive letter, and appending it during the Copy-Item, but it doesn't seem to work either. (e.g: C:\folder\file becomes \folder\file in the list.)
I created test directory to just help show the issue, of examples of files/folders that I want to grab (purely for testing, the real files are multiple locations/file types).
- test_dir_cmd
- folder
- folder1
* file2.db
* file3.json
* file2.txt
* file3.js
- folder2
* file.bak
* file.db
* file.txt
* temp.dat
This method works for folders and their contents, but not for specific files or wildcard.
"\USERS\$USER\AppData\Local\test_dir_cmd\folder\folder1",
"\USERS\$USER\AppData\Local\test_dir_cmd\folder\*.txt",
"\USERS\$USER\AppData\Local\test_dir_cmd\*\file.db",
"\USERS\$USER\AppData\Local\test_dir_cmd\temp.dat”
This is an example of how the list of files I'll need to get is presented and I'll need to work with.

Any help and advice on how I can fix this would be greatly appreciated!
The issue is that you are not joining the paths well. You do this:
-Destination "$triage_location\$path"
At that point $triage_location is C:\temp\output\Triage\c and $path is something like \USERS\TMTech\AppData\Local\test_dir_cmd\folder\folder1. You just make the path with string expansion but since $path starts with a \ and you include that in your string, so your string comes out looking like this:
"C:\temp\output\Triage\c\\USERS\TMTech\AppData\Local\test_dir_cmd\folder\folder1"
Use Join-Path instead:
Copy-Item (Join-Path 'C:\' $path) -Destination (Join-Path $triage_location $path) -Force -Recurse

How to remove duplicate files from an arraylist

A bit different from the others. I'm retrieving an arraylist of files for processing (basically handling DLL registration on a local machine), and I need my script to properly handle multiple DLLs with the same name. The select -Unique doesn't work, since technically the files aren't duplicates - each has its own unique full path.
I need this script to retrieve all DLLs in a folder (as well as sub-folders), but only return the last instance of each named file. For example if I have files:
C:\Path\Update1\GRM.DLL
C:\Path\Update1\HTCP.DLL
C:\Path\Update2\GRM.DLL
C:\Path\Update3\GRM.DLL
The script should return the objects for Update3\GRM.DLL and Update1\HTCP.DLL.
[System.Collections.ArrayList]$dlls = #(Get-ChildItem -Path $PSScriptRoot -Recurse | Where-Object
{$_.Extension -eq ".dll" -and $_.FullName -notmatch 'dll_Old'})
Edit: Got it going with this, but it's selecting the first instance that shows up, and I need the last. In this example, that means it's snagging Update1/GRM.DLL instead of Update3/GRM.DLL
$dlls = #(Get-ChildItem -Path $PSScriptRoot -Recurse | Where-Object {$_.Extension -eq ".dll" -and $_.FullName -notmatch 'dll_Old'}) | Select-Object -Unique
Use a hashtable to keep track of the last file seen for a specific file name:
$files = #{}
Get-ChildItem -Path $PSScriptRoot -File -Recurse -Filter *.dll |Where-Object FullName -notmatch 'dll_Old' |ForEach-Object {
$files[$_.Name] = $_
}
$uniqueFiles = $files.Values
Mathias R. Jessen's helpful answer is probably the best (fastest) solution in this case, but here's an alternative based on the Group-Object cmdlet:
Get-ChildItem -LiteralPath $PSScriptRoot -Recurse -Filter *.dll |
Where-Object FullName -notmatch dll_Old |
Group-Object Name |
ForEach-Object { $_.Group[-1] }
Group-Object Name groups all matching files by their .Name property.
ForEach-Object { $_.Group[-1] } then extracts the last (-1) member from each resulting group.
Note that Group-Object will implicitly sort the groups by the grouping property, so the resulting list of file-info objects (System.IO.FileInfo, as output by Get-ChildItem) will be sorted by file name.

How to search Powershell array for specific strings and use this result in a copy-item -include script

I'm trying to create a synchronization script in Powershell so that my applications in MDT are being copied on a regular basis to our main file server, based on the folder name (in MDT, applications are in one folder, where our main server has applications split depending on the department who uses them).
From what I read on the web, the best way would be to populate an array with "Get-ChildItem", which I kinda figured how to do (see code below).
After the array is populated though, I don't know how to search that array for specific results, nor do I know how to use those results with copy-item.
In a nutshell, here's what I need to do: Build an array using "Get-ChildItem", query the resulting array for specific folders, and have those folders be copied to specific destinations.
Here's the code I have so far:
$arr = Get-ChildItem \\slmtl-wds02.domain.inc\deploymentshare$\applications |
Where-Object {$_.PSIsContainer} |
Foreach-Object {$_.Name}
$sourcepath = \\slmtl-wds02.domain.inc\deploymentshare$\applications
$destSLARC = \\slmtl-fs01.domain.inc\folder\it_services\private\software\service_desk\pc\SLARCMTL
$destSLMTL = \\slmtl-fs01.domain.inc\folder\it_services\private\software\service_desk\pc\SLMTL
$destSLGLB = \\slmtl-fs01.domain.inc\folder\it_services\private\software\service_desk\pc\SLGLB
$destSLTECH = \\slmtl-fs01.domain.inc\folder\it_services\private\software\service_desk\pc\SLTECH
Thanks in advance for your help :)
$sourceLocation = "c:\analysis\"
$targetLocation = "c:\analysisCopy\"
$included = #("folder1", "folder2")
$result = #()
foreach ($i in $included){
$result += get-ChildItem $sourceLocation -filter $i | Where-Object {$_.PSIsContainer}
}
$result | foreach-Object { copy-item $_.FullName -Destination $targetLocation -Recurse}
Hope this works change the path D:\ to your desired path enter the name of folder you looking for
$Keyword=[Microsoft.VisualBasic.Interaction]::InputBox("Enter your Query")
[System.Reflection.Assembly]::LoadWithPartialName('Microsoft.VisualBasic') | Out-Null
Get-ChildItem D:\ -recurse | Where-Object {$_.PSIsContainer -eq $fasle -and $_.Name -match "$keyword"} | Copy-Item -Destination d:\test

Loop/Cycle through Subdirectories and determine file count in each

I have the directory E:\NugetRoot\NugetServer where I need to cycle through the subdirectories on this path and within the packages folder within that subdirectory I need to count the files ending in .nupkg and output them to a cvs file named d:\monitoring\NugetStatistics and each time the script is run, it should append to the file.
Count the files ending in .nupkg in "C:\NugetRoot\NugetServer\\**\Packages" for each folder. (I need to Loop through the ** folders and count each file ending on .nupkg)
Output in cvs file with two columns: one showing the "**" folder name & the other showing the file count.
First find all the *.nupkg files using Get-Childitem with the recurse flag to get all files in sub folders, then filter the results using a regex to exclude any where the final folder is not called Package. Then use another regex to extract the previous folder name, feed that in to a Group-Object to get the count and then into a Export-Csv which includes the append flag.
cd E:\NugetRoot\NugetServer
Get-ChildItem -Filter *.nupkg -Recurse | ? {
$_.DirectoryName -match '\\Packages$'
} | % {
$_.DirectoryName -Replace '^.*\\([^\\]+)\\Packages$', '$1'
} | Group-Object | Select Name, Count | Export-Csv outfile.csv -Append -NoTypeInformation
cd "C:\NugetRoot\NugetServer\\**\Packages"
$a = Get-ChildItem -Name
foreach ($i in $a) {
$b = (Get-ChildItem -Recurse -Force -Include .nupkg -Path $i | Select-Object -ExpandProperty Name).Count
$i + "`t" + $b
}
Here's what I have so far. It displays the server name, ProjectgroupID(or folder name), but get error for package count. Also, I am having trouble getting the average file size as well, I commented those out:
$folders = gci C:\NuGetRoot\NugetServer -Directory
foreach($folder in $folders){
#{ServerName=$env:COMPUTERNAME;
ProjectGroupID = $folder.Name;
NuGetPackageCount = (gci $folder.FullName\packages -Include '*.nupkg') | %{$_.Size}.Count;
#AverageSize= Measure-Object (listof sizes) -Average
} #| Export-Csv -Path c:\temp -NoTypeInformation -Append
}
Measure-Object -Average

Read entries from text file into a variable in PowerShell

I hope someone can help me. I am pretty new to PowerShell and can't really script it myself with the exception of looking at existing code and modifying it.
I have found a PowerShell script that reports file share permissions for a specific share and recurses through the subfolders returning their permissions as well.
My problem is I need to do this with a lot of shares so would like to be able to provide the script with a text file containing the share names. I know I need to do a for each loop and read the names of the shares in a text file into an array but I don't know how to do this. I guess it's pretty simple for someone with more experience.
This is the script i have used with single entry.
http://mywinsysadm.wordpress.com/2011/08/17/powershell-reporting-ntfs-permissions-of-windows-file-shares/
#Set variables
$path = Read-Host "Enter the path you wish to check"
$filename = Read-Host "Enter Output File Name"
$date = Get-Date
#Place Headers on out-put file
$list = "Permissions for directories in: $Path"
$list | format-table | Out-File "C:\scripts\$filename"
$datelist = "Report Run Time: $date"
$datelist | format-table | Out-File -append "C:\scripts\$filename"
$spacelist = " "
$spacelist | format-table | Out-File -append "C:\scripts\$filename"
#Populate Folders & Files Array
[Array] $files = Get-ChildItem -path $path -force -recurse
#Process data in array
ForEach ($file in [Array] $files)
{
#Convert Powershell Provider Folder Path to standard folder path
$PSPath = (Convert-Path $file.pspath)
$list = ("Path: $PSPath")
$list | format-table | Out-File -append "C:\scripts\$filename"
Get-Acl -path $PSPath | Format-List -property AccessToString | Out-File -append "C:\scripts\$filename"
} #end ForEach
Sorry for the noob question. I plan to learn more when I have a bit more time but any help now would be massively appreciated.
Thanks in advance.
If you have a share name on each line within your text file can put all the shares into an array like this:
$path = "C:\ShareNames.txt"
$shareArray = gc $path
To access the first share you can use this syntax:
$shareArray[0]
