Export-CSV with the output path as a variable - powershell

Question

Is there a way I can export the list to a text file and separate them by share name somehow, not single file?
I'd like to do in this format, "$hostname-$sharename.txt".
Here is what I have so far:
$Shares = Get-WmiObject Win32_Share -Filter "not name like '%$'" |
Select-Object -Expand Path
$re = ($Shares | ForEach-Object {[Regex]::Escape($_)}) -join '|'
$results = foreach ($Share in $Shares) {
(Get-ChildItem $Share -Recurse | Select-Object -Expand FullName) -replace "^($re)\\"
}
$results | Out-File -FilePath "C:\Output\$($env:computername)-$sharename.txt"

Answer 1

If I understand the question correctly, all you are missing in your code is the sharename part for the various output files.
Below will hopefully do what you want:
$outputDir = 'C:\Output'
$Shares = Get-WmiObject Win32_Share -Filter "not name like '%$'"
$re = ($Shares | ForEach-Object {[Regex]::Escape($_.Path)}) -join '|'
foreach ($Share in $Shares) {
$result = (Get-ChildItem -Path $Share.Path -File -Recurse | Select-Object -Expand FullName) -replace "^($re)\\"
# output the results per share in a text file
$fileOut = Join-Path -Path $outputDir -ChildPath ('{0}-{1}.txt' -f $env:COMPUTERNAME, $Share.Name)
$result | Out-File -FilePath $fileOut -Force
}
