count

PS D:\> $directory
\\NOL-A0049001\D$\089228b5520c384a86

$directory | gm ==> returns system string.

In the above, there is a record.

If i do a $directory.count, it gives $null and not ONE

How do i ensure there is a scalar value in the $directory.count ?

Try it myself :

$mycount = $directory | measure-object -property length -sum

$mycount.count ==> at least it gives a number count.

Let me know if u guys have other solutions.

if ($directory){do something}

Force the result to array so it will always have a count property even when
there is only
one item:

@(dir $directory).count

I always use If ($Object) {..}

That is equivalent of "If Exist $Object". You can use same for If
($Object.Count) {...}, which can be translated as "If not $Object.Count is
Nothing"...

PoSh [11] » $directory = "\\NOL-A0049001\D$\089228b5520c384a86"
PoSh [12] » @(dir $directory).count
Get-ChildItem : Cannot find path '\\NOL-A0049001\D$
\089228b5520c384a86' because it does not exist.
At line:1 char:6
+ @(dir <<<< $directory).count
0

Throws an error because the path doesn't exist, but still shows the
count 0.


PoSh [13] » $directory = "C:\windows\desktop.ini"
PoSh [14] » @(dir $directory).count
1

Found one file and shows count.

Hope that helps.

Is it hidden? If so add -force to dir.
