I needed this once when I was trying to refresh the Library share. It failed on refresh with an error saying that a DVD was in use and wouldn't refresh until it was no longer in use. The following commands allowed me to identify the machines.

In general all of these need:

{{{#!highlight powershell
Import-Module VirtualMachineManager
}}}

== Get a list of Virtual Machines that have a DVD attached ==

{{{#!highlight powershell
Get-SCVMMServer -ComputerName Samuel

== List VMs at the end of the semester to be deleted ==

{{{#!highlight powershell

}}}

== Get a list of VM Mac Addresses for CPTR 427 ==

{{{#!highlight powershell

Here is a list of Power Shell Scripts that are too cool to ignore

For the uninitiated:

Symbol

Meaning

%

shortcut for foreach object

$_

current object in the pipeline

Get-Member

Will list the fields of the object you send it

Sort-Object -Property [property name]

Will sort the objects you send in by the property name(s) which can be a comma separated list

Where-Object {$_.property -like '*string*'}

Will filter the objects

Get-Command -Module PSWindowsUpdate

Lists all the commands in the PSWindowsUpdate module

Windows and AD Scripts

Expand all zip files into directories with zip name

   1 $list = Get-ChildItem | ? { $_.Name -like "*.zip" } | select Name
   2 foreach ($line in $list) {
   3     $parts = $line.Name.Split(".")
   4     $outDir = ".\" + $parts[0]
   5     $inFile = $line.Name
   6     mkdir $outDir
   7     Expand-Archive $inFile -DestinationPath $outDir 
   8 }

List of Listening Ports with their owning programs

   1 $listening = (Get-NetTCPConnection | ? {($_.State -eq "Listen") -and ($_.RemoteAddress -eq "0.0.0.0")})
   2 foreach ($l in $listening) {
   3     $procid = $l.OwningProcess
   4     $proc = Get-Process -PID $procid | SELECT ID,ProcessName
   5     Write-Host $($l.LocalPort) "||" $($procid) "||" $proc.ProcessName
   6 }

List of AD accounts and the last time they logged in

   1 Get-ADUser -Filter * -SearchBase "dc=home,dc=scotnpatti,dc=com" -ResultPageSize 0 -Prop CN,samaccountname,lastLogonTimestamp | 
   2      select CN, samaccountname,@{n="lastLogonDate";e={[datetime]::FromFileTime($_.LastLogonTimestamp)}} 

List Memory Installed

   1 Get-WmiObject win32_physicalmemory | Format-Table Manufacturer,Banklabel,Configuredclockspeed,Devicelocator,Capacity,Serialnumber -autosize

List object from Registry - namely version of .NET installed

Replace a string in a file using a regular expression

So I downloaded a bunch of files from "the way back machine" site and I needed to update the hard-coded links to be relative site links. The following little script did it for me.

   1 $files = ls Level*.html
   2 foreach ($item in $files) {
   3     (Get-Content -path $item) | % { $_ -Replace '(https://web.archive.org/nebula/level)([0123456789]{2})/', 'Level$2.html' } | Set-Content $item
