Essential PowerShell Snippets

File Manipulation

Copy a file

Copy-Item -Path "C:\Path\to\source\file.txt" -Destination "C:\Path\to\destination\folder"

Move a file

Move-Item -Path "C:\Path\to\source\file.txt" -Destination "C:\Path\to\destination\folder"

Delete a file

Remove-Item -Path "C:\Path\to\file.txt" -Force

Rename a file

Rename-Item -Path "C:\Path\to\oldfile.txt" -NewName "newfile.txt"

Retrieve System Information

$computerInfo = Get-WmiObject -Class Win32_ComputerSystem
$operatingSystem = Get-WmiObject -Class Win32_OperatingSystem

$manufacturer = $computerInfo.Manufacturer
$model = $computerInfo.Model
$totalMemory = [math]::Round($computerInfo.TotalPhysicalMemory / 1GB, 2)
$operatingSystemName = $operatingSystem.Caption
$osVersion = $operatingSystem.Version

Write-Host "Manufacturer: $manufacturer"
Write-Host "Model: $model"
Write-Host "Total Memory (GB): $totalMemory"
Write-Host "Operating System: $operatingSystemName"
Write-Host "OS Version: $osVersion"

In the above code, we use the Get-WmiObject cmdlet to retrieve system information. We fetch information about the computer system using the Win32_ComputerSystem class and information about the operating system using the Win32_OperatingSystem class.

The example retrieves the manufacturer, model, total physical memory (in gigabytes), operating system name, and operating system version. It then displays the retrieved information using the Write-Host cmdlet.

Please note that you may need administrative privileges to run certain WMI queries depending on the system configuration.

User Management

Create a new user account

New-LocalUser -Name "JohnDoe" -Password (ConvertTo-SecureString "P@ssw0rd" -AsPlainText -Force) -FullName "John Doe" -Description "New User"

Modify user account properties

Set-LocalUser -Name “JohnDoe” -Description “Updated Description” -PasswordNeverExpires $true

Remove a User Account

Remove-LocalUser -Name "JohnDoe"

Enable or Disable a User Account

Disable-LocalUser -Name "JohnDoe"
Enable-LocalUser -Name "JohnDoe"

Add User to a Group

Add-LocalGroupMember -Group “Administrators” -Member “JohnDoe”

Remove User from a Group

Remove-LocalGroupMember -Group "Administrators" -Member "JohnDoe"

Please note that some of these commands may require administrative privileges to execute successfully. Adjust the user account name, password, and other parameters as needed for your specific use case.

Replacing Spaces with an Underscore

Renaming files can be a laborious task, especially when there’s a lot to get through. This command renames all files within your current directory which have a space in the file name, and replaces it with an underscore, for example; ‘I need this.jpg’ changes to ‘I_need_this.jpg’.

Dir | Rename-Item –NewName { $_.name –replace “ “,”_” }

Listing File Names

This command will list all file names in the current directory and put it into a text file. The text file will be saved into the current directory.

ls > filename.txt
