按子文件夹列出文件数

Question

I am trying to use powershell to produce a list of folder names and how many files are in each folder.

I have this script

$dir = "C:\Users\folder" 
Get-ChildItem $dir -Recurse -Directory | ForEach-Object{
    [pscustomobject]@{
        Folder = $_.FullName
        Count = @(Get-ChildItem -Path $_.Fullname -File).Count
    }
} | Select-Object Folder,Count

Which lists the file count, but it puts the full path (ie C:\\Users\\name\\Desktop\\1\\2\\-movi... ). Is there any way to just display the last folder ("movies") as well as save the result to a .txt file?

Thank you

Answer 1

Instead of $_.FullName , use $_.Name to only get the directory name .

Your Select-Object call is redundant - it is effectively a no-op.

While it's easy to send the results to a .txt file with > , for instance, it's better to use a more structured format for later programmatic processing. In the simplest form, that means outputting to a CSV file via Export-Csv ; generally, however, the most faithful way of serializing objects to a file is to use Export-CliXml .

Using Export-Csv for serialization:

$dir = 'C:\Users\folder'
Get-ChildItem -LiteralPath $dir -Recurse -Directory | ForEach-Object {
    [pscustomobject] @{
      Folder = $_.Name
      Count = @(Get-ChildItem -LiteralPath $_.Fullname -File).Count
    }
} | Export-Csv -NoTypeInformation results.csv

Note that you could streamline your command by replacing the ForEach-Object call with a Select-Object call that uses a calculated property :

$dir = 'C:\Users\folder'
Get-ChildItem -LiteralPath $dir -Recurse -Directory |
  Select-Object Name,
    @{ n='Count'; e={@(Get-ChildItem -LiteralPath $_.Fullname -File).Count} } |
      Export-Csv -NoTypeInformation results.csv

Answer 2

You mean something like this...

Clear-Host
Get-ChildItem -Path 'd:\temp' -Recurse -Directory | 
Select-Object Name,FullName,
@{Name='FileCount';Expression = {(Get-ChildItem -Path $_.FullName -File -Recurse| Measure-Object).Count}} `
| Format-Table -AutoSize
