Powershell: dynamic -summary switch to get-childitem

[p0W3RH311]

please add a dynamic -Summary switch to get-childitem in filesystem

Steps to reproduce

PS C:\> Get-ChildItem C:\Users


    Directory: C:\Users


Mode                LastWriteTime         Length Name
----                -------------         ------ ----
d-----       10/13/2018   5:11 AM                FOO
d-r---        8/22/2013   8:36 AM                BAR
d-----       10/16/2018   5:50 AM                BAZ
------       10/16/2018   5:50 AM              0 LOL

   Summary: 4 items, 3 Directory, 1 File(s)

the summary must be written in host and not written in pipe

Size would be nice in the summary too. .

It's pretty straightforward to get this information, too, so I don't see any reason not to go for this...

# Sum of length = total size ; count of length = total files
# Sum of PSIsContainer = total directories
Get-ChildItem | Measure-Object -Property Length, PSIsContainer -Sum

Now, granted, on a length recursive search, adding that information to every section of the default output might be a bit much and slow things down slightly, but I suppose that it really wouldn't add an unreasonable amount of processing if it's only being done for the display formatting.

Seems we have dup. I can not find the issue /cc @lzybkr

As for implementation we could internally create (recursively for every directory) special psobject with statistics and output it to pipeline to get output like cmd.exe. Only formatting system should be enhanced to understand this.

@iSazonov - you were thinking of https://github.com/PowerShell/PowerShell/issues/2376

[thezim]

How about human readable output for numbers, e.g. KB, MB, GB, etc.
