How do I count the total number of rows returned from a WQL query?

I am trying to find the total number of CPUs on a computer via get-wmiobject. The query: select * from win32_processor returns more than 1 row if there is more than 1 processor on the computer. WQL doesn't have the count keyword like in TSQL. So I am just wondering whether there is another way to find the total number of rows returned?

Solution

  • You can just force it into an array and use the Count property:

    @(gwmi win32_processor).count

    For the specific case, if you are just looking for number of processors, you can do:

    $env:NUMBER_OF_PROCESSORS
