如何使用PowerShell解析Windows命令`wmic`的output

Question

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.

Answer 1

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 .

Answer 2

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
