Simplify PS Command: Get-Service | where {($ _. Status -eq "Stopped") -OR ($ _. Status -eq "Running")}

Question

What is the syntax for including multiple values ​​in the -eq command:

This works, but I think there is a way to preserve some typing:

Get-Service | where {($_.Status -eq "Stopped") -OR ($_.Status -eq "Running")}

Thinking what the code should look like, but I definitely don’t remember the syntax:

Get-Service | where {($_.Status -eq "Stopped"|"Running"|"...")}

Answer 1

You can use an -containsalias gsv:

gsv | where-object {@("Stopped","Running") -contains $_.Status}

EDIT . You can also use the operator -match:

gsv | where-object {$_.Status -match "Stopped|Running"}

2.EDIT : a shorter version, with special thanks to @Joey:

gsv | ? {$_.Status -match "Stopped|Running"}

Answer 2

@OcasoProtal, -contains -notcontains.

, (.. ). (.. ValidateSet) Enum (, , Not).

clear-host
[string]$ComputerName = $env:COMPUTERNAME
[string]$ServiceName = "MSSQLSERVER"


function Wait-ServiceStatus {
    [CmdletBinding()]
    param
    (
        [Parameter(Mandatory = $true)]
