In this update, you’ll see how I added two or three new scripts to the environment and also changed how most of the scripts work.

One new script that I add was a script that would take CSV data and add the users to a group in Active Directory. You can see this below:

function Get-CSVAddToGroup{
 <#
 .SYNOPSIS
 This function allows you to add usernames from a CSV to a specified Active Directory group.
 It needs confirmation for each addition to a group.

 .EXAMPLE
 Get-CheckCSVAddToGroup -Groupname "all rossendale staff" -path c:\testing\test.csv

 #>
 [cmdletbinding()]
 param(
 [parameter(Mandatory=$true)]
 [string]$groupname,

 [parameter(mandatory=$true)]
 [string]$path
 )

 $csvformembership = Import-Csv -Path $path

 foreach ($b in $csvformembership){
  $name = $b.user
  Add-ADGroupMember -Identity "$groupname" -Members $name -Confirm
 }
}

Another script I added was my script for sending messages to remote computers on the network. You can see this below:

function Send-Message{

 function send-messagewithname{
  $name = Read-Host "Enter a name"
  $msg = Read-Host "enter a message"
  $adcompstocheck = Get-ADComputer -LDAPFilter "(name=$name)" -Properties name

  if ($adcompstocheck -eq $null){
   Write-Host "$name doesn't exist!"
   pause
  }else{
   Invoke-WmiMethod -Path win32_process -Name create -ArgumentList "msg * $msg" -ComputerName "$name"
  }
 }

 function send-messagewithip{
  $ip = Read-Host "enter an IP"
  $msg = Read-Host "enter a message"
  $adcompstocheckip = Get-ADComputer -Filter * -Properties ipv4address, name | select ipv4address
  if ($adcompstocheckip -eq $null){
   write-host "$ip doesn't exist"
   pause
  }else{
   Invoke-WmiMethod -Path win32_process -Name create -ArgumentList "msg * $msg" -ComputerName "$ip"
  }
 }

 do {$nameorip = Read-Host "Do you want to use IP or Name (I or N)?"} while (("i","n") -notcontains $nameorip)
 if ($nameorip -eq "n"){
  send-messagewithname
 }else {
  send-messagewithip
 }
}

Finally, my last script that was added to my custom PowerShell environment allowed me to list all the computers on the network with a specific operating system. For example “2012” or “Professional”. The code for this is below:

function list-OSVersonComputers{
 <#
 .SYNOPSIS
 This function allows you to list all of the computers with the requested OS version.

 .EXAMPLE
 List-OSVersionComputers -OSVersion 2012

 .EXAMPLE
 List-OSVersionComputers -OSVersion standard
 #>
 [cmdletbinding()]
  param(
  [parameter(mandatory=$true)]
  [string]$OSVersion
 )

 $OSVersion2 = '*' + ($OSVersion) + '*'

 Get-ADComputer -Filter {OperatingSystem -like $OSVersion2} -Property * | Format-Table name,operatingsystem,lastlogondate -Wrap -AutoSize
}

I also added help menus to most of my scripts to make them more professional.
