Powershell 以表格形式获取子文件夹列表和每个文件的数量

Question

I'd like to create a table showing the number of files in all subfolders named "andre tegninger" I've found the following code on here which I modified to filter by the sub folder I am interested in.

dir -filter "*Andre tegninger*" -recurse |  ?{ $_.PSIsContainer } | %{ Write-Host $_.FullName (dir $_.FullName | Measure-Object).Count }

This works fine but is there a way I can get name of folder and number of files in two separate columns? Thank you!

You can use Select-Object to get in separate fields the expected properties:

dir -filter "*Andre tegninger*" -recurse | ?{ $_.PSIsContainer } | Select-Object -Property FullName, {(dir $_.FullName | Measure-Object).Count}

Since -Property expect a property (obviously) You have to use {} around (dir $_.FullName | Measure-Object).Count to tell powershell it's a calculated expression.

You're getting as output:

FullName      (dir $_.FullName | Measure-Object).Count
--------      --------------------------------------
Your list of folders...

You can label the fields names to get them some fancy names, such as:

dir -filter "*Andre tegninger*" -recurse | ?{ $_.PSIsContainer } | Select-Object -Property @{label="Path";expression={$_.FullName}}, @{label="Numer of files";expression={(dir $_.FullName | Measure-Object).Count}}

And you get as output:

Path     Numer of files
