I am trying to parse the output of:
wmic copmutersystem
and
net.exe config workstation
using PowerShell to get an object as Key/Value pair and/or convert it to JSON String.
I know there is a PowerShell equivalent command:
Get-CimInstance -Class Win32_computersystem
But the ask here is to figure out how to use PowerShell to parse a similar output for wmic CMD line.
Wmic can output csv or xml, but obviously get-wmiobject or get-ciminstance is preferred. You just need to find the class names instead of the aliases. The creator of wmic and powershell is the same.
wmic computersystem list /format:csv | convertfrom-csv | select model
Model
-----
OptiPlex 7490 AIO
List wmic class aliases:
wmic alias list brief
wmic alias where "friendlyname = 'computersystem'" list brief
wmic alias where "friendlyname like '%comp%'" list brief
FriendlyName PWhere Target
ComputerSystem Select * from Win32_ComputerSystem
For example:
ComputerSystem Select * from Win32_ComputerSystem
get-ciminstance win32_computersystem
Use the Get-CimInstance and ConvertTo-Json commandlets:
Get-CimInstance -Class Win32_ComputerSystem | ConvertTo-Json
Edit: Previous revision of this answer used Get-WMIObject, but that's been deprecated.
Get-CimInstance -Class Win32_ComputerSystem instead.
Get-CimInstance -Class Win32_computersystem. Thank you. However, my intension of the question is how to parse a similar output if there is no equivalent command in PowerShell. I will update the question.
Get-CimInstance is preferable: The CIM cmdlets (e.g., Get-CimInstance) superseded the WMI cmdlets (e.g., Get-WmiObject) in PowerShell v3 (released in September 2012). Therefore, the WMI cmdlets should be avoided, not least because PowerShell (Core) v6+, where all future effort will go, doesn't even have them anymore. Note that WMI still underlies the CIM cmdlets, however. For more information, see this answer.
