This command will give some properties of an ls item:

PS> (ls)[0]|select *

PSPath            : Microsoft.PowerShell.Core\F...
PSParentPath      : Microsoft.PowerShell.Core\F...
PSChildName       : myscript
PSDrive           : C
PSProvider        : Microsoft.PowerShell.Core\F...
PSIsContainer     : True
Mode              : d-----
BaseName          : myscript
Target            : {}
LinkType          :
Name              : myscript
FullName          : C:\ps\myscript
...

I want to count how many line the output have.

This post gives a solution based on Measure-Object to count a CSV, but it is not applied here. Is there any method to do this? As I count one by one,the last result should be 23.

You could do `(((ls)[0]|select *|Out-String) -split '\r?\n' |?{$_}).Count`, or you could do `@((ls)[0].psobject.properties).Count` - but *why*? – Mathias R. Jessen Jul 14 '17 at 11:15
What are you really after? Are you looking for `DirectoryInfo`'s properties? – vonPryz Jul 14 '17 at 11:18
@MathiasR.Jessen I cannot find your `psobject` from `(ls)[0]|Get-Member` – yode Jul 14 '17 at 11:21
@yode: that's because `Get-Member` will not list `psobject`. But it does exist on every object. And if you already know about `Get-Member`, why haven't you used `(Get-Member -MemberType Properties).Count`? – Jeroen Mostert Jul 14 '17 at 11:22
@vonPryz I just want to count how many line the output of `(ls)[0]|select *` – yode Jul 14 '17 at 11:23

@yode `(ls)[0] | Get-Member -Force` – Ansgar Wiechers Jul 14 '17 at 11:23
@AnsgarWiechers Thanks.. – yode Jul 14 '17 at 11:27
@MathiasR.Jessen What's meaning of your `?` in your `'\r?\n'`?And I think that comment deserve a answer for reading.. – yode Jul 14 '17 at 11:27
@yode `\r?` means the carriage return character (`\r`) is optional. – Ansgar Wiechers Jul 14 '17 at 11:30

@yode Again, *why* would you want to count the number of output lines? – Mathias R. Jessen Jul 14 '17 at 11:32
@MathiasR.Jessen Well,I really have no specific aim.I just curious about how to do. :) – yode Jul 14 '17 at 11:33
