Search directory for unique path and patterns

Question

I am trying to search a directory structure, and files for all instances of where a pattern exists. Than I want that file location recorded in a log file that I can review latter. I looked at various posts, but I have not found a similar example where this is happening. Reviewed posts include:

Here is the code I am using to recuse through the folder structure:

#Set variables for paths
$Results = "C:\Results"
$Source = "C:\Test\*"
$Destination = "C:\MyTest\"

#Create file name for each report with date and time of run
$ReportDate = (Get-Date).ToString("dd-MM-yyyy-hh-mm-ss")

$CustomPattern = Read-Host 'What pattern are you looing for?'
$CustomPatternLog = New-Item -itemType File -Path C:\Results -Name $("CustomerPattern_" + $ReportDate + ".txt")
$CustomPattern = foreach ($file in Get-ChildItem -Path $Destination -Recurse | Select-String -pattern $CustomPattern | Select-Object -Unique Path) {$file.path}
$CustomPattern > "$($Results)\$($CustomPatternLog)"

However, this code is returning the following error:

Get-ChildItem : The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters. At line:19 char:36 + $CustomPattern = foreach ($file in Get-ChildItem -Path $Destination -Recurse | S ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : ReadError: (C:\Test\Mor...ofiles\Customer:St ring) [Get-ChildItem], PathTooLongException + FullyQualifiedErrorId : DirIOError,Microsoft.PowerShell.Commands.GetChil dItemCommand

Do you have a better way to do the same operation?

replace this

$CustomPatternLog = New-Item -itemType File -Path C:\Results -Name $("CustomerPattern_" + $ReportDate + ".txt")
$CustomPattern = foreach ($file in Get-ChildItem -Path $Destination -Recurse | Select-String -pattern $CustomPattern | Select-Object -Unique Path) {$file.path}
$CustomPattern > "$($Results)\$($CustomPatternLog)"

with this

$files = Get-ChildItem -Path $Destination -Recurse

#in case you would need the path replace FullName with PsParentPath
$result = ($files | ?{$_.name -like "*$CustomPattern*"}).FullName 
$result | out-file ($CustomPattern + "_" + $ReportDate + ".txt")

and since its shell you can do the same with one liner

(Get-ChildItem -Path $Destination -Recurse | ?{$_.name -like "*$CustomPattern*"}).FullName | out-file ($CustomPattern + "_" + $ReportDate + ".txt")
