diskusage how to use in powershell - powershell

Question

I am very new to powershell and writing a script which will go to each computer in windows domain and get the size of a user profile. I have tried below on a powershell script
$profileDir = "\\$computerName\c$\users\userProfile"
$fullProfile = (Get-ChildItem $profileDir -recurse -force | Measure-Object -property length -sum)
But on some computer it gives below error. The problem seems that some directories on the profile have a long path and get-ChildItem fails
Get-ChildItem : The specified path, file name, or both are too long. The fully
qualified file name must be less than 260 characters, and the directory name mu
st be less than 248 characters.
At C:\scripts\powershell\profiles.ps1:56 char:30
+ $fullProfile = (Get-ChildItem <<<< $profileDir -recurse -force | Measure-Obj
ect -property length -sum)
+ CategoryInfo : ReadError: (\\computerName...nt.IE5\RQT4K4JU:St
ring) [Get-ChildItem], PathTooLongException
+ FullyQualifiedErrorId : DirIOError,Microsoft.PowerShell.Commands.GetChil
dItemCommand

At this point I tried using du.exe (diskusage) from SysInternals which works fine but I don't know how to take the output of du into a variable. I have below on my script
$dirSize = .\du.exe -c c:\temp |convertFrom-csv | select-object DirectorySize
write-host $dirSize
The output is
PS C:\scripts\powershell> .\profiles.ps1
#{DirectorySize=661531}
What I want the output to be like
PS C:\scripts\powershell> .\profiles.ps1
661531

Answer 1

What you have is a hashtable. You need to reference the item in that hashtable to get it's value. Instead of:
Write-Host $dirSize
Try:
$dirSize['DirectorySize']
