Before you begin, make sure you have the following:

  1. Windows Environment: PowerShell is readily available on most Windows systems.
  2. Basic Command Line Familiarity: We'll be working with the command line interface.

Step-by-Step Guide

1. Define Your Target Directory

In our PowerShell script, start by defining the directory path where you want to search for text files. Assign the path to a variable for better management. Replace `"C:\Path\To\Your\Directory"` with the actual path to your desired directory.

```powershell $targetDirectory = "C:\Path\To\Your\Directory" ```

2. Retrieve Text Files

Next, use the `Get-ChildItem` cmdlet to retrieve a list of all text files (files with the `.txt` extension) in the specified directory and its subdirectories. Use the `-Recurse` parameter to include subdirectories in the search.

```powershell $textFiles = Get-ChildItem -Path $targetDirectory -Filter "*.txt" -Recurse ```

3. Iterate and Display

Iterate through each text file in the list using a `foreach` loop. Display the full path of each file using the `Write-Host` cmdlet.

```powershell foreach ($file in $textFiles) { Write-Host "Text file found: $($file.FullName)" } ```

Running Your Script

  1. Open a PowerShell command prompt or PowerShell ISE (Integrated Scripting Environment).
  2. Navigate to the directory where you've saved your PowerShell script.
  3. Run the script by entering `.\YourScriptName.ps1` (replace `YourScriptName` with your script's actual name).


By following this guide, you've successfully created a basic PowerShell script that efficiently lists text files in your specified directory and its subdirectories. This accomplishment marks just the beginning of what PowerShell can achieve. As you continue your exploration of PowerShell, you'll uncover a world of possibilities. From managing system configurations to automating complex tasks, PowerShell empowers you to streamline your workflows and make the most out of your programming journey. Dive deeper into the realm of cmdlets, delve into advanced scripting techniques, and unlock the true potential of automation.
