Powershell Where-Object Match

I want to use the Where-Object to limit the Output of Get-PSDrive to only network shares.

Get-PSDrive shows me the following:

Name           Used (GB)     Free (GB) Provider      Root                                       CurrentLocation

Variable                               Variable                                                                
W                 197.72               FileSystem    \\192.168.71.32\perf200                                   
WSMan                                  WSMan                                                                   
X                 197.72               FileSystem    \\192.168.71.32\perf100                                   
Y                 271.52         34.33 FileSystem    \\192.168.71.30\group200                                  
Z                 271.52         34.33 FileSystem    \\192.168.71.30\group100

Then I want to get the \\192.168.71.30\group100 Network Share:

Get-PSDrive | Where-Object  { $_.Root -match "\\\\192.168.71.30\\group100" }

But I get nothing, why does -match not work?

Use DisplayRoot instead of Root property

Get-PSDrive | Where-Object  { $_.DisplayRoot -match "\\\\192.168.71.30\\group100" }

try to run

Get-PSDrive | Where-Object  { $_.DisplayRoot -match "\\\\192.168.71.30\\group100" } | select *

Root will be your mapped drive letter, and DisplayRoot your UNC Path

EDIT: as a side note. For escaping regex use [regex]::Escape() method. 

PS > [regex]::Escape("\\192.168.71.30\group100")
\\\\192\.168\.71\.30\\group100

If yoy type Get-PSDrive | select root you will notice that for network drives it will print nothing. So there is something strange with network share roots.

Get-PSDrive | select root | %{write-host $_.Root.GetType()} will show that it's a system string, so not quite sure why it seems to be empty for network drives.

Try using -eq instead:

Get-PSDrive | Where-Object {$_.Root -eq "\\192.168.71.30\group100"}
