PowerShell Scripting - WmiObject Win32_Share

PowerShell Scripting - WmiObject Win32_Share

The purpose of this script is to list shares on a server.  In fact, this code will enumerate the shares on any computer.

WMI and PowerShell Topics

• Preliminary: Get-WmiObject
• Examples of WmiObject win32_share
• Summary of WmiObject Win32_Share

 ♣

Preliminary: Get-WmiObject

I admit that there is a danger of getting side tracked when we start experimenting with these command.  My justification is that research WMI properties is useful in other contexts.

Get-WmiObject -list
or even
Get-WmiObject -list |where {$_.name -like "win32*"}

Note 1: See how the production line is controlled by the pipe | in the middle.

Note 2: Remember that 'where' {takes curly brackets}. 

Note 3: Observe that 'like' is a parameter or switch, thus needs a minus sign: -like.

Five Examples of WmiObject win32_share

1) Initial Investigation

To display a list of all the objects properties, never miss an opportunity to employ:
Get-Member

Get-WmiObject win32_share | Get-Member

2) Basic

Get-WmiObject win32_share

3) Switch to a named server

Get-WmiObject win32_share -computer YourBigServer

Note: Naturally, change the name of YourBigServer to the name of a machine on your subnet.

4) Filter Properties Path, then Name, but NO Description

WmiObject win32_share | ft path, name -autosize

Note: Redundant Option removed: (Get-)WmiObject
Note: ft means format-Table.  Other options are format-list or format-custom.

5) Display Shares, which are not hidden

WmiObject win32_share | Where {$_.name -notlike "*$"} | sort-Object -property path | ft path, name -autosize

Note1: Strictly speaking the term is where-Object, however, I removed the redundant noun -object.  You could also try omitting '-object' from 'sort-Object

Challenge: Try: Where {$_.name -like "*$"}

Summary of Scripting PowerShell Shares

Firstly, remember that win32_share is a WmiObject.  Secondly, once you have mastered the basics you may wish to filter the shares by using a 'Where' statement.  Finally, you may wish to modify the number and position of the properties displayed in the output.
