Get-ChildItem | Write-Host
The command in the title lists all the short names of files and folders in the current folder, whereas `Get-ChildItem * | Write-Host` lists the full names (including paths). I compared the output of `Get-ChildItem | gm` with the output of `Get-ChildItem * | gm`: no difference. If the very same objects are piped into Write-Host, how can the cmdlet give consistently different outputs?
"VBAF Learning Trail -- From Zero to AI Developer in PowerShell 5.1"
VBAF -- Getting Started A Guided Trail from Zero to AI Developer Welcome. You are about to learn how artificial intelligence actually works -- not by reading about it, but by running it, watching it, and breaking it. VBAF implements neural networks, reinforcement learning and multi-agent systems from scratch in PowerShell 5.1. Every algorithm is readable. Every concept is explained in the code comments. This guide takes you from installation to building your own AI agent. Follow the camps in order. Do not skip ahead. Time required: 2-4 hours for Camps 0-3. Camps 4-5 are open-ended. CAMP 0 -- BASECAMP Get VBAF installed and your first output on screen Goal: see "VBAF Framework ready!" on your screen Step -- Install VBAF from PSGallery**Title:** VBAF -- educational AI and reinforcement learning framework in pure PS 5.1
Hello, I have been building an educational framework for learning AI concepts in PowerShell 5.1 and wanted to share it with this community. VBAF (Visual AI & Reinforcement Learning Framework) implements neural networks, Q-learning, DQN, PPO and A3C from scratch -- no Python, no external dependencies, no cloud services. The goal is to make AI concepts accessible to PowerShell developers. Every algorithm has full comments explaining the mathematics in plain English, with references to the original research papers. Quick start: ```powershell Install-Module VBAF -Scope CurrentUser . .\VBAF.LoadAll.ps1 # See a neural network learn XOR & .\VBAF.Core.Example-XOR.ps1 # Train a DQN agent on CartPole $agent = (Invoke-DQNTraining -Episodes 50 -FastMode)[-1] $agent.PrintStats() ``` The framework also includes a multi-agent market simulation where four company agents compete using Q-learning -- price wars, innovation races and tacit collusion emerge naturally without being programmed. For teachers: docs/teaching/ contains a 4-week course outline, lab exercises and exam questions. GitHub: https://github.com/JupyterPS/VBAF PSGallery: https://www.powershellgallery.com/packages/VBAF Happy to answer any questions about the implementation choices or the PS 5.1 class system quirks.

The off-line help files of all parameters of all cmdlets have the answer False to the question in the title. This is confusing and wrong. And since I'm at it: the 3rd and 4th syntax item of the off-line help file of Get-Help miss the parameters -Examples, -Parameters, respectively (compared to the syntax items of the on-line help). I'm a learner of PowerShell and find it tiresome that the off-line help is unreliable and that I have to go to the online help so often. I use Windows PowerShell version 5.1.26100.8457
Powershell Entra and General Forum Layout Questions
Hello, I am returning to PowerShell, and it seems a lot has changed. I need to create some Security Groups in MS Entra and would like to know the best way to do so. I have a .csv file for the groups. Also, what is the best way to display the topic titles as a list in this forum? At this moment, I have to go scroll through pages of posts, and it's not easy. I used to like the old formats that let you see all the thread titles. ThanksError PowerShell 300-1015 (80)

Gui to deploy folder contents to multiple VMs
I am trying to improve imaging computers where I work. I need to create a gui for new hires since the imaging process is so complicated. I need the GUI to request necessary computer names that are being imaged and then copy files from a local workstation to the machines that are being imaged on the network that our technicians do not have physical access to. I have turned to Powershell for the solution in an attempt to improve on my knowledge which is basic really. Below is the code I have come up with so far. In this code I am getting the location of the file. I would rather copy the entire folder instead of the file but I couldnt find the code to do that. So, if that is possible please show me how. If not I figure I would have to save these imaging files to a ZIP file. Then I could maybe use this GUI I am working on to move the zip file to the remote computers. Add-Type -AssemblyName System.Windows.Forms # Create the form $form = New-Object System.Windows.Forms.Form $form.Text = "File and Network Location Collector" $form.Size = New-Object System.Drawing.Size(400, 200) # Create the label for file name $fileLabel = New-Object System.Windows.Forms.Label $fileLabel.Text = "File Name:" $fileLabel.Location = New-Object System.Drawing.Point(10, 20) $form.Controls.Add($fileLabel) # Create the text box for file name $fileTextBox = New-Object System.Windows.Forms.TextBox $fileTextBox.Location = New-Object System.Drawing.Point(100, 20) $fileTextBox.Size = New-Object System.Drawing.Size(250, 20) $form.Controls.Add($fileTextBox) # Create the label for network location $networkLabel = New-Object System.Windows.Forms.Label $networkLabel.Text = "Network Location:" $networkLabel.Location = New-Object System.Drawing.Point(10, 60) $form.Controls.Add($networkLabel) # Create the text box for network location $networkTextBox = New-Object System.Windows.Forms.TextBox $networkTextBox.Location = New-Object System.Drawing.Point(100, 60) $networkTextBox.Size = New-Object System.Drawing.Size(250, 20) $form.Controls.Add($networkTextBox) # Create the button to submit $submitButton = New-Object System.Windows.Forms.Button $submitButton.Text = "Submit" $submitButton.Location = New-Object System.Drawing.Point(150, 100) $form.Controls.Add($submitButton) # Add event handler for the button click $submitButton.Add_Click({ $fileName = $fileTextBox.Text $networkLocation = $networkTextBox.Text [System.Windows.Forms.MessageBox]::Show("File Name: $fileName`nNetwork Location: $networkLocation") }) # Show the form $form.ShowDialog() In this portion of the code it is copying from one source to many locations. Thank you for any assistance as this would help my organization a lot. We are getting several new hires who are very new to the industry. This would be a huge blessing. Pardon the change in font size. It did that for no reason, its my first time using the blog, and there appears to be no way to change the sizes lol. Forgive me. #Define the source folder and the list of target computers $sourceFolder = "C:\Path\To\SourceFolder" $destinationFolder = "C:\Path\To\DestinationFolder" $computers = @("Computer1", "Computer2", "Computer3") # Replace with actual computer names # Function to copy the folder function Copy-Folder { param ( [string]$source, [string]$destination ) Copy-Item -Path $source -Destination $destination -Recurse -Force } # Execute the copy operation on each computer foreach ($computer in $computers) { Invoke-Command -ComputerName $computer -ScriptBlock { param ($source, $destination) Copy-Folder -source $source -destination $destination } -ArgumentList $sourceFolder, $destinationFolder } Write-Host "Folder copied to all specified computers."
