What is the best to way to do this?

Answer 1

try this:

$DirList=@('C:\temp\BATCHHISTOCRE', 'C:\temp\tmp', 'C:\temp\444')

$DirList | %{

    [pscustomobject]@{
    Dirname=$_
    NbFile=(Get-ChildItem -Path $_ -File).Count # Add -recurse if you want all tree into your dir
     }
}

Tagging on to @Esperento57: , helpful answer.

Yeppers, it does work, but it will also error off if the folder path has no files; whereas using Measure-Object in the mix, can address that.

$DirList = @('D:\Temp\AddressFiles',
'D:\Temp\BonoboGitServer',
'D:\Temp\Book'
)

$DirList | 
ForEach-Object {
    [pscustomobject]@{
        Dirname = $PSItem
        NbFile  = (Get-ChildItem -Path $PSItem -File).Count
    }
}
# Results
<#
Dirname              NbFile
-------              ------
D:\Temp\AddressFiles      3
The property 'Count' cannot be found on this object. Verify that the property exists.

Whereas using the Measure-Object cmdlet, addresses the issue...

$DirList = @('D:\Temp\AddressFiles',
'D:\Temp\BonoboGitServer',
'D:\Temp\Book'
)

$DirList | 
ForEach-Object {
    [pscustomobject]@{
        Dirname = $PSItem
        NbFile  = (Get-ChildItem -Path $PSItem -File | 
                  Measure-Object).Count
    }
}
# Results

-------                 ------
D:\Temp\AddressFiles         3
D:\Temp\BonoboGitServer      0
D:\Temp\Book                 4
