Just access the Priority
property of the object returned from the pipeline:
$var = (Get-WSManInstance -enumerate wmicimv2/win32_process).Priority
(This won't work if Get-WSManInstance
returns multiple objects.2)
For the second question: to get two properties there are several options, problably the simplest is to have have one variable* containing an object with two separate properties:
$var = (Get-WSManInstance -enumerate wmicimv2/win32_process | select -first 1 Priority, ProcessID)
and then use, assuming only one process:
$var.Priority
and
$var.ProcessID
If there are multiple processes $var
will be an array which you can index, so to get the properties of the first process (using the array literal syntax @(...)
so it is always a collection1):
$var = @(Get-WSManInstance -enumerate wmicimv2/win32_process | select -first 1 Priority, ProcessID)
and then use:
$var[0].Priority
$var[0].ProcessID
1 PowerShell helpfully for the command line, but not so helpfully in scripts has some extra logic when assigning the result of a pipeline to a variable: if no objects are returned then set $null
, if one is returned then that object is assigned, otherwise an array is assigned. Forcing an array returns an array with zero, one or more (respectively) elements.
2 This changes in PowerShell V3 (at the time of writing in Release Candidate), using a member property on an array of objects will return an array of the value of those properties.
