A slightly dirty Powershell module which includes a function for converting the results of the command-line Query User in to a Powershell object and a function for logging off disconnected users (with -whatif and -confirm).
# Example usage:
# Get-RDPUser | Disconnect-RDPUser -WhatIf
Function Get-RDPUser {
[CmdletBinding()]
Param()
query user | Select -Skip 1 | ForEach-Object {
$_ = $_ -split "\s\s+"

Param(
$PRTGURL = "https://{your PRTG URL}/api",
$Auth = "username={your PRTG user}&passhash={your PRTG password hash}",

Powershell uses of Select-String to filter a log file and example Regular Expressions for identifying IP addresses and IP spaces
#This regex matches anything that's like an IP address (even invalid ones)
$regexIPAddress = '\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b'
#This regex matches anything like an IP address that starts 10, 172 or 192
$regexIPSpace = '(10|172|192).\d{1,3}\.\d{1,3}\.\d{1,3}\b'
#Returns the first IP address in each line of the log file/s then sorts and removes duplicates.
Select-String -Path *.log -Pattern $regexIPAddress | ForEach-Object { $_.Matches } | % { $_.Value } | Sort-Object -Unique | Out-File 'UniqueIPs.txt'
#Returns from a selection of Log files any lines which match a certain string pattern
