Powershell script to see currently logged in users (domain and machine) + status (active, idle, away)

In search of this same solution, I found what I needed under a different question in stackoverflow: Powershell-log-off-remote-session. The below one line will return a list of logged on users.

query user /server:$SERVER

There's no "simple command" to do that. You can write a function, or take your choice of several that are available online in various code repositories. I use this:

function get-loggedonuser ($computername){

#mjolinor 3/17/10

$regexa = '.+Domain="(.+)",Name="(.+)"$'
$regexd = '.+LogonId="(\d+)"$'

$logontype = @{
"0"="Local System"
"2"="Interactive" #(Local logon)
"3"="Network" # (Remote logon)
"4"="Batch" # (Scheduled task)
"5"="Service" # (Service account logon)
"7"="Unlock" #(Screen saver)
"8"="NetworkCleartext" # (Cleartext network logon)
"9"="NewCredentials" #(RunAs using alternate credentials)
"10"="RemoteInteractive" #(RDP\TS\RemoteAssistance)
"11"="CachedInteractive" #(Local w\cached credentials)
}

$logon_sessions = @(gwmi win32_logonsession -ComputerName $computername)
$logon_users = @(gwmi win32_loggedonuser -ComputerName $computername)

$session_user = @{}

$logon_users |% {
$_.antecedent -match $regexa > $nul
$username = $matches[1] + "\" + $matches[2]
$_.dependent -match $regexd > $nul
$session = $matches[1]
$session_user[$session] += $username
}


$logon_sessions |%{
$starttime = [management.managementdatetimeconverter]::todatetime($_.starttime)

$loggedonuser = New-Object -TypeName psobject
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Session" -Value $_.logonid
$loggedonuser | Add-Member -MemberType NoteProperty -Name "User" -Value $session_user[$_.logonid]
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Type" -Value $logontype[$_.logontype.tostring()]
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Auth" -Value $_.authenticationpackage
$loggedonuser | Add-Member -MemberType NoteProperty -Name "StartTime" -Value $starttime

$loggedonuser
}

}

Since we're in the PowerShell area, it's extra useful if we can return a proper PowerShell object ...

I personally like this method of parsing, for the terseness:

((quser) -replace '^>', '') -replace '\s{2,}', ',' | ConvertFrom-Csv

Note: this doesn't account for disconnected ("disc") users, but works well if you just want to get a quick list of users and don't care about the rest of the information. I just wanted a list and didn't care if they were currently disconnected.

If you do care about the rest of the data it's just a little more complex:

(((quser) -replace '^>', '') -replace '\s{2,}', ',').Trim() | ForEach-Object {
    if ($_.Split(',').Count -eq 5) {
        Write-Output ($_ -replace '(^[^,]+)', '$1,')
    } else {
        Write-Output $_
    }
} | ConvertFrom-Csv

I take it a step farther and give you a very clean object on my blog.

I ended up making this into a module.
